Barty sat there, close by, trying to be - something. Comforting? Helpful? Supportive? Whatever Evan needed, whatever it was. He didn't know. He had never...experienced something like that. And he hadn't tried to ever help someone, but he was going to because he loved Evan, and there was nothing more important. Nothing. He wanted to get Evan away from all the people that likely could confuse him, many of whom hated him, and didn't care for Evan like Barty did.
But he was grateful to have Gina explain it all to Evan. She was a healer and understood more about it. Barty would...do whatever they suggested because hell, whatever would help. What helped with this? He had to stop asking the same question a hundred times in his head. Barty couldn't freak out, not in front of Evan, not while Evan was awake. Evan was damaged so much more. And Barty had to be there for him, be everything.
Barty nodded slightly to Gina upon what she said. And he knew he didn't care to complete the few remaining interviews. Augustus could do that. Or Severus. Someone. Barty had to be there for Evan. Barty tried to give Evan a comforting smile.
Then oh yes. "I'm Barty," he introduced himself, "I'll be here for you, always, every moment. If there's anything you need, just ask." And no matter what it was, Barty was there to get it for him. Barty loved him.
