Steve observes the one-sided conversation with a small grin, one that almost instantly disappears when Kate looks his way again. Her words pretty much confirm everything he's already deduced about her - the faces she prefers to show the world, the sides she favors over others. He's caught a glimpse of at least two or more just within this one conversation, and he gets the feeling that there are likely more. Her admissions only confess so much, and he knows she's still keeping him at a distance despite the closer proximity they've achieved during their talk. Close, but leagues apart.

"Why take items that don't count as anything of value to you?" he asks, peering over at her, a deep frown settling in on his face. "You had to have known that some of them had sentimental value to their owners, otherwise you wouldn't have bothered leaving much more than the note. You saw the box under the bed, and you knew that it meant something because of where it was hidden." More accurately, he'd placed the box under the bed as a reminder that it'd always be there, that his father's investigation was still ongoing in one way or another, even if there was another version of himself still pursuing the endgame.

"A simple thief would have taken items worth more than just the memories," Steve finishes, propping his foot up a step higher, his forearm rising as it continues to rest on his knee. "This wasn't just about what you could do. This was about what? What you didn't do? What are you trying to prove, Kate?"
