Henry knew what Izura did and just smiles as Charlie deserved that little tease cause of her song making Charlie to realized the teasing and blushes even more as Cassidy took her off the stage to rest making the other three, but Gabriel to call the two mama and mommy.

'Got it right.' Izura thinks as she saw Henry walking onto the stage and she wonders what he'll sing, but she knows it's about her father and the business making Izura to hate her uncle Vincent for what he made her father do to those children and his friendship with Henry.

'Glad I did that to him then.'

'Oooooooh big time. He deserved it.' Both sides of Izura agrees to do that again to him after a couple of weeks.

"Connection terminated
I'm sorry to interrupt you
If you still even remember that name
But I'm afraid you've been misinformed
You are not here to receive a gift
Nor have you been called here by the individual you assumed
Although you have been deep involved (This is based on Henry Emily's ending speech in the true ending of  Fives Nights at Freddy's 6; Pizzeria simulator. The actual part of the speech goes as follows: 'Connection terminated I'm sorry to interrupt you Elizabeth If you still even remember that name. But I'm afraid you have been misinformed. You are not here to receive a gift. Not have you been called here by the individual you assumed although you have indeed been called.')

It was long ago we were friends (They were best friends until Henry found out what "he'' did to the six children...)
Thought we could build a world of innocent fun
Should have known better that you were too far gone
Was I really that blind? You were doing something else (Yes, yes u were. Henry was "blind" because William and Henry were going to try and build "innocent fun" for children but something happened when 6 children went missing (cough): William. He killed 6 children including Charlotte/Charlie/puppet/lefty henrys daughter.)
Couldn't even trust you to be a human being (That is cold henry just very cold. he could barely even trust Willam because he found out what happened with the missing children... I understand what u mean henry U-U)
You don't have a heart, you're a cold dark monster
And if I didn't know then, well I know now

Can't tell you how ashamed I feel (Why not u can just say "I am very ashamed" that is easy henry. He is ashamed because he "trusted " his best friend, who turns out to be a monster/killer.)
There's so many dead and I can't seem to grasp
How this is real!
Don't you tell me "This is all for a purpose"
You know they didn't deserve this!
And now you're gonna pay for what you did!
Now you're gonna pay for what you did!
Oh, just remember as the flames grow
All your sins crawl down below!

It all started back in the 1980's (This is when Willam first started killing. Also the decade when two of his children die and the first few games are set.)
Opened up a place where there would be tragedies (Henry Emily refers to the pizzeria he opened, where William committed his crimes.)
Had a lot of evil plans that I just couldn't see
How could I have worked with such a monstrosity?
Just because that you had faced a loss
Doesn't mean that you can take something away from me! (Henry is basically saying "Just because you lost your children does not mean you can take mine away from me.")
I don't give a damn about the pain you could have felt!
Don't take that out on me!

Now you're gonna pay for what you did!
Oh, just remember as the flames grow
All your sins crawl down below!

Oh, I'm gonna send you down to Hell (This Is a reference to NightCove _theFox's Five Nights at Freddys song "Send Me Down to hell." The is also referencing one of Henry Emily's lines in the true ending speech, from Five Nights at Freddys 6; Pizzaria Simulator. 'Although, for one of you, the darkest pit of Hell has opened to swallow you whole. So, don't keep the Devil waiting, old friend.")." Henry finished his song.

'I may have forgive you, William... I don't forgive Vincent cause this is all his fault fully.' Henry thinks to himself as Vincent still owes him big time for this making Vincent to know what he means and keeps trying making them to be people who just met each other a couple of times only.
