from @bllakcat: i hope i'm not interrupting anything.
you would think that sebastian, trained as he is, dangerous as he is, would recognize the sneaky footsteps of an approaching figure on this rooftop... but no. instead, as it always seems to be when felicia comes around, sebastian is startled, almost shouting when she speaks and breaks his concentrated silence. if he didn't have such a firm grip on his sniper rifle, he'd have thrown it off the roof in fright. "my god!" sebastian immediately palms the front of his chest to soften his breathing, shaky laughter billowing from his lungs. "you... you're really good at that, you know. you should do that for a living." that's the joke. "my god, felicia, you scared me. give me a second to catch my breath before i fall over with shock."
he crouches back down beside the hard-shell case he's working over, tugging pieces of his rifle out of the protective foam as he constructs the weapon to its full-length, dangerous form. now that he's calming down, sebastian gives felicia another peek. she's as casual as ever. hand on her hip, eyes trained curiously on his work. some things never change. "do you make it a point to follow me around and pop up on the same rooftop as i'm on? is that intentional, or was this on accident?" then, a pause, and he squints. "or maybe, in the chaos of my hit, you can sneak into the penthouse and steal their jewelry while they're all panicked inside. maybe that's why you're here. you're like a hyena at a lion's kill. that's smart of you." another lengthy pause, and sebastian stands. "missed you, by the way. how've you been? staying out of trouble?"
