He could still remember the fight and how it had ended with the spiked shield; it surprised him to some degree that the... whatever-it-was that sourced Jaime's power didn't force some kind of reaction. That wasn't the sort of thing you were supposed to let register on your face in front of someone who probably continued to have guilt of one kind or another over it, though, and it wasn't as if he actually held that incident against the other teenager in any way, so he continued to maintain the outward appearance of feeling neutral about the meeting. No good making the other think he'd done something wrong. Again.

Doubly important when considering the downward spiral of Jaime's personal life as of late.

"Hey," Trowa replied, in no great hurry to bombard the other with useless niceties or pointless small talk.

Turning his attention from his friend to the steps underfoot, he 'hmm'ed thoughtfully and tapped the toe of his boot against the steps at a spot that was neither too close nor too far away from where Jaime presently happened to be.

"This staircase taken?"
