Tony.
Tony ordered an avengers meeting to discuss the Steve situation. Steve had showed signs of hearing them and trying to react to them, but it wasn't enough to wake him up.
He allowed Bucky to stay with Steve, the ex-assasin got very restless if he had to leave Steve for something short as going to the bedroom. Tony wasn't taking the risk of making him sit through a chaotic meeting with possibility of triggering the winter soldier.
Thereby, Tony and Bucky had agreed there should always be someone with Steve while he was in this state. Just in case he woke up and needed someone of his family close. The best one to be there was Bucky, even if Steve's brain suffered damage and he wouldn't remember the avengers, he would remember Bucky.
"So, what's the plan?" Natasha crossed her long legs and looked at Tony.
"Should I contact the healers of Asgard?" Thor asked.
"I am a brain surgeon, maybe I should check..." Strange thought aloud. Bruce and Clint just sat amidst the chaos. Tchalla and Scott arrived too and took their seats.
"Mr. Stark?" Everyone grew quiet as the newest member of the avengers piped up. "can... Do you think Mr. Barnes would mind if I visited Mr. Rogers?"
Tony smiled warmly at his doe-eyed protégée.
"I think maybe Steve would like that. He sees us as his family, maybe he needs his family to fight through this and wake up. We should make sure we aren't as chaotic as we are right now, that would only stress him out."
"So, we visit cap and say we're all here for him?" Sam Wilson summarised.
"I think we should go in pairs and if that goes Well, we can do a group visit, to calmly." He emphasized that last word.," Support him and make sure he feels loved and safe. I'll take the kid to see him first, Wilson, I think he'd like you and Natasha to come next."
The pair nodded, and Thor proposed he'd come after them to cheer Bucky up a bit as well.
"That's kind of you, Thor. I'll let Bucky know." Tony promised the god."Clint, Bruce. You balance each other out, maybe you could go after Thor. "
Then he looked at tchalla.
"Your highness, would you mind going for a visit tonight together with Scott?"
"I'll do anything to help a friend." Tchalla nodded, and Tony smiled.
"Great. Class dismissed."
