I'm another one who keeps her pups compartmentalized and as unaware of one another as possible; they never interact ICly, and any kind of OOC interaction is purely theoretical (or, like Gen put it, flashes of characterbleedy reaction to something going on in another pup's thread). I'd go crazy trying to keep it straight otherwise.

Embracing the theoretical, though? Predictably, Sylar hates everybody -- especially Mercer, which Mercer finds hi-larious. Ellen keeps a wary eye on both of them as she goes about her business; she's a little warmer toward Mac by virtue of them both knowing Sam Winchester, but Mac's pretty quiet and busy with her own stuff most of the time. Sam the Shoulder Angel's never around unless he takes a wrong turn, *poofs* in by mistake, and immediately *poofs* out again after a hasty apology.

There are also a couple of Hawaiian shirts haphazardly tossed around the place. Like Wash would leave for good without giving them something to remember him by.
