The genius held Steve's gaze, his thumb nail tapping against the metal almost affectionately. "Not being able to handle being the reason for killing the most important thing in its life." His voice was low, soft and almost off key at points. He lowered his eyes, letting them go out of focus as some sort of memory pulled at the corners of his mind before he snapped back to the present.

"You always have a home with me." He said it fast. Automatically. Like nothing else could be clearer or simpler in the world. But he never would have said that out loud before. Well... he would, but not so plainly. "When you get lost... you can come home." To him. If Steve could even call him home...

Shaking his head, he didn't know if he wanted to hear the answer to that offer. Instead he grinned as Steve climbed up onto the mushroom with him. Turning his body, he shifted until he partially laid across the blonde. Much like before, he curled an arm on Steve's chest and rested his cheek on the back of his hand as he looked up at him.

"Can't think of anything else I want more right now." His eyes drooped slowly, the tiredness seeping in like he could just sleep the day away. "You are very warm." And that made it all the more reasonable for why he needed the good captain as a pillow.
