Your pov:
We finally got all the stones. I'm still sad about tasha but loki has helped me a lot. He has been acting distant lately. I don't know whats happening to him. I'm have to find him and ask him what's happening.
You went to go find loki and ask him what was happening. But when you finally found him Tony just had to cut you off and talk about the stones. I know I know that's what the real problem is but it hurts me to see him like this.
"We got all the stones and now... Who's gonna snap?" Tony asks without making eye contact with anyone. You stand up and start talking. "I will. I don't want any of you to get hurt" You say rubbing your arm. Loki stands up quick and yells no. "No, I will not allow that." He said with a stern look on his face. "Who died and made you the boss of me. No one. That's what I thought." You roll your eyes at him. You didn't mean to be mean but you didn't want anyone to get harmed. Loki started to talk but bruce cut him off. "I'll do it" You both looked at him with a hell no face. "No you can't do it. I'm not letting any of you u get hurt. Got it?" You say with an angry tone. Loki hit the wall and yelled again. "No. I don't care. You are not doing it. Okay. I will do it myself if I have to." You were a little scared by his yelling. He had never yelled at you like that before. "No I said I would do it" Bruce stood in between you and Loki. Everyone else was just silent. You finally gave up and Bruce took the gauntlet and put it on. You can see the pain in his eyes as the stones flowed through his body. He got all his strength and snapped. It didn't feel any different but then clints phone rings. You run towards him and see it's his wife. "Guys, I think it worked" We all heard scott say. Then all of a sudden the building was hit.
Loki's pov:
It worked. Everything was back to normal. I look at y/n in shock. Right when I was about to walk over and spin her around in my arms the building was hit. I woke up covered in stone and dust. I couldn't control my coughing and I used my powers to free myself. I stood up and realized something. Y/n. "Y/n!? Where are you? Can you hear my voice? Please love answer me?" All of a sudden Tony appeared in tears. "I- I can't find her anywhere."

Sorry it's so short. Im having writers block.
