[Oh, it's this guy! Yusuke blinks, seeming a little taken aback when he sees Riku frowning back at him. He remembers him, sort of - mostly as that kinda smug, annoying long-haired dude who'd showed up to give him crap when he first got here. The memory sits badly with him, especially now that he's finding himself angry about being stranded here again, so it's not long before Yusuke's expression becomes guarded again, his jaw tightening and his lips pressing into a thin line. He's obviously not exactly pleased to see Riku, but he keeps his mouth shut and decides to hear Riku out anyway, since - again - the thought of actually getting to do something useful around here is pretty tempting.

By the time Riku's finished speaking, Yusuke feels - and looks - a little less hostile. He'd half-expected Riku to give him some kind of wishy-washy bullshit response like "oh, but sitting on your butt doing jackshit to help anybody even if it's in your power to help them is okay too. if that's what you want to do", but he didn't, and that earns him at least a couple points in Yusuke's book. That said, Yusuke still has questions, so without further ado, he says:]

"PGC", huh. What's that supposed to stand for? And what exactly do you guys do? I'm guessing it's something a little more specific than just "fighting bad guys".
