Rex glances down at the terrarium again, putting two and two together quickly enough. He nods then, taking a quick look around, gets to unlocking the door.

"If you could carry that..." He motions to the terrarium, then pushes the door open. Despite housing several projects, the lab is fairly clean and orderly, each project set clearly apart from the other. It may turn into a cluttered wreck throughout the day, but he's always sure to put everything back in place before he leaves. The projects range from medical equipment to crystal-powered security robots-- contracted for a merchants whose warehouse had been broken into one too many times-- and there's a prototype for something that looks kind of like a bionic eye sitting half-complete on one of the desks.

Overall, it looks like a fairly innocent workshop. That's because the weapons he's been working on are down (some for Ana, and some just in case) in the basement, the entrance to which is covered by one of the tables. It's a pain in the ass to move every time he needs to get down there, but he'll take that inconvenience over somebody accidentally finding the trapdoor (which was basically the selling point of this particular lab).

"So." He tosses his messenger bag on one of the few empty surfaces. "Did you come around to ask me about the feeding habits of snakes?"
