Vision waited patiently for Tony to see him before he moved from his spot near the door. He was eager to speak with his creator, but had previously been cautioned on his condition and the android didn’t want to risk rushing in and potentially overwhelming him. The android had searched for and watched footage on what had happened, the big final battle and Tony’s heroic actions that ended the entire battle. Watching it, Vision was convinced that there was no way that he could have survived that. He expected to see Tony die right there, and had been visibly shaken when he had seen him lying there.
It wasn’t until he had spoken more with the others that he was informed Tony had survived. He had been doubtful at first- all evidence suggested otherwise, but wanted to trust the team wouldn’t lie about something that serious. Still, he had wanted to see him himself. Still, he stood by the door until he heard Tony’s voice. His face breaks into a smile, and he has it in him to at least look sheepish. “My apologies, Tony. Old habits die hard I suppose.” He’s pleased to hear that he’s happy to see him, and the feelings are certainly mutual.
Approaching the bed, Vision sits himself down on a chair close by, and settles his hands in his lap. “Before Thanos arrived... Shuri attempted to remove the stone from my head. Unfortunately we ran out of time.” He shifts a little on his seat and looks away, a little uncomfortable discussing it but there was no way to avoid this. “The only way to stop him was to destroy the stone. We- Wanda and I, tried.” The android continues, turning back to face Tony once more. “I... Uploaded my memory to the internet- I recalled Jarvis did something similar a few years prior. I trusted one day they would find a way to bring me back.”
Frankly, Vision was relieved that they had found him and brought him back. He knew there was an immense risk that he would be lost forever. However, the android had known that was all he could do. Whether it was by Wanda’s or Thanos’s hand- Vision knew he wasn't going to make it through the battle. “I suppose...” He paused, and his lips curled into a smile. “I suppose I developed quite the self sacrificial streak from all my time with you.” The android’s tone is teasing, hoping to lighten the mood a little.
