Rachel was not happy, she had to leave the hospital to and go confront the one and only Sebastian Smythe. Everyone in the New Directions including her ex fiancee Finn (Who cheated on her with Quinn again) made her go, she didn't want to, but she didn't have a choice, but deep down she was a little excited, because if she gets a chance to have a duet with him, she gets to know if their voices blended well together like she hopes, but she will never tell anyone that, secretly she likes that Sebastian gets under her skin.

Rachel knew that she had a fiery side, but she didn't want Sebastian to know that, but here she was walking around Dalton towards The Warblers choir room, wearing a black skin tight knee length dress with a pair stilettos and black hat, looking for Sebastian to find out what he had put in the slushie that hit Blaine. 

Before she entered the choir room, she took out the tape and microphone, stepped on it, and threw it in the bin. Once she broke the tape and threw it away, she walked in the choir room she saw The Warblers but no Sebastian. She was about to ask where he was but then she heard

"Well, well, well, what do we have here." She turned and saw the one and only Sebastian Smythe, before she could answer, he held up a slushie, and as he threw it, Rachel ducked and the slushie landed on a warbler. Everyone in the room including Sebastian all gasped that someone had dodged a slushie.

Rachel stood up, confronted Sebastian and said

"Practice from always getting slushied at McKinley." Before she could say anything more, the boy who got slushied by Sebastian ran out of room to change his blazer. Once he left, Rachel stood her ground and said

"Thanks to you, Blaine has to have eye surgery." As she said that one of the warblers said

"Omg is Blaine okay." Before she could answer, Sebastian said

"I got this Nick." As soon as Sebastian said that, Rachel glared at him, placed her hands on her hips and said

"What did you put in that slushie?" Sebastian smirked and said

"Red Dye number 6." Rachel rolled her eyes and said

"You are lying, Red Dye number 6 doesn't do much damage to the eyes, now what did you put in that slushie?" Sebastian folded his arms and said

"I told you." Rachel faked laugh and then said

"and I told you that I didn't believe you." Sebastian looked at Rachel and then said

"How dare you question my honour." Rachel rolled her eyes, and Sebastian then said

"Warblers leave." As Sebastian said that all The Warblers had left the choir room, leaving only Rachel and Sebastian alone. Rachel was nervous because Sebastian could do anything to her, but she shook away her nerves, and walked up to him and said

"Let's duel Streinsand."

Sebastian
Uh, as he came into the window
It was the sound of a crescendo, uh!
He came into her apartment
He left the bloodstains on the carpet, uh!
She ran underneath the table
He could see she was unable
So she ran into the bedroom
She was struck down, It was her doom
Annie are you OK?

Rachel:
So, Annie are you OK?

Sebastian
Are you OK, Annie?

Rachel
Annie are you OK?

As they sang they chased each other, it was a game of cat and mouse, and they were both determined to win

Sebastian
So, Annie are you OK?

Rachel
Are you OK, Annie?

Sebastian
Annie are you OK?

Rachel
So, Annie are you OK?

Sebastian
Are you OK, Annie?

Rachel
Annie are you OK?

As they sang, Rachel was super excited because she had been right, their voices did blend well together

Sebastian
So, Annie are you OK?

Rachel and Sebastian (Sebastian)
Are you OK, Annie?
Annie are you OK?
Would you tell us that you're OK (Uh!)
There's a sign in the window
That he struck you - a crescendo Annie
He came into your apartment
He left the bloodstains on the carpet (Uh!)
And then you ran into the bedroom
You were struck down
It was your doom

They continued singing, and Rachel wasn't sure if Sebastian was truly gay or not, because he had been looking her up and down, and even Sebastian had been confused about it all, because lately all he could think about was Rachel

Sebastian
Annie are you OK?

Rachel
So, Annie are you OK?

Sebastian
Are you OK Annie?

Rachel
Annie are you OK?

Sebastian
So, Annie are you OK?

Rachel
Are you OK Annie?

They continued singing, neither one giving up on their cat and mouse game, Sebastian was surprised that Rachel could keep up with him vocally, because not even The Warblers can keep up with him.

Sebastian
Annie are you OK?

Rachel
So, Annie are you OK?

Rachel and Sebastian
Are you OK Annie?

Sebastian
You've been hit by

Rachel
You've been hit by

Rachel and Sebastian:
A Smooth Criminal

Sebastian
Uh, So they came into the outway
It was Sunday - What a black day, uh!
Mouth to mouth resuscitation
Sounding heartbeats - Intimidations
Annie are you OK?

Neither one was giving up, Sebastian could see Rachel was having second thoughts about something, but he didn't know what, but he wasn't going to use it against her, not when he is amazed and mesmerised by how well their voices blended well together.

Rachel
So, Annie are you OK?

Sebastian
Are you OK Annie?

Rachel
Annie are you OK?

Sebastian
So, Annie are you OK?

Rachel
Are you OK Annie?

Sebastian
Annie are you OK?

Rachel
So, Annie are you OK?

Sebastian
Are you OK Annie?

Rachel
Annie are you OK?

Sebastian
So, Annie are you OK?

They continued singing and dancing around the choir room. Rachel was having second thoughts about Finn, and she knew that Sebastian knew, but she was surprised that he wasn't using against her

Rachel and Sebastian
Are you OK, Annie? Annie are you OK?
Would you tell us that you're OK
There's a sign in the window
That he struck you - a crescendo Annie
He came into your apartment
He left the bloodstains on the carpet, uh!
And Then you ran into the bedroom
You were struck down
It was your doom
Annie are you OK?
Are you OK Annie?

Sebastian
You've been hit by

Rachel:

A Smooth Criminal

The song came to an end, and they stood in front of each other, Rachel had her leg wrapped around him, and Sebastian stared at Rachel and then at her lips, and then at her eyes, and she said

"Kiss me, Finn and I have already broke up, he chose Quinn." Sebastian kissed Rachel, and to his surprised Rachel had kissed him back, and much more to his surprise he enjoyed it as well, and will admit to himself that it's the best kiss he has ever had. They pulled away for oxygen, and Rachel had said

"Thanks to you, my best friend has to have eye surgery, what did you put in the slushie ." Sebastian stared at her and she said that, he looked into her eyes and he saw concern and fear, he was worried, and he said

"Rock salt, but it's a shame about Blaine, I was actually aiming for Finn and Quinn." Rachel was surprised at his confession and said

"Why?" Sebastian stepped away from Rachel and said

"Because I know he cheated on you with Quinn." Rachel was surprised that he would defend her, and she said

"But why would you defend me, no-one defends me." Sebastian walked towards Rachel, kissed her again, and when they pulled apart he said

"Because I like you more than I should, and I want to be with you." Rachel was shocked but kissed him again, and then said

"I want to be with you."
