It's not like Caroline not to be there late at night, and at first, Klaus thinks it might be that the lift's refusing to take her up to their floor. It wouldn't be the first time. Sometimes, they also get locked in their room, or out of it. But he lets her be, anyway, and he paints, instead. He's been thinking about his time in Narnia again, since he first drank from Regina, and he needs something to occupy his brain.
The brushes have taken a little used to, but he likes the new style it's created, in his hand. Something he's never done before, but something he still meant to do. And painting calms him down; it's always calmed him down. He's taken the biggest canvas he has, and he's painted something in dark colours, glowing eyes in the night, shapes of almost beings, and yet it's nowhere near as eerie as he'd set out for it to be, and he likes it that way. It's not actually threatening, and it was a pleasant realisation, halfway through, when he could still have taken it in another direction. It's not threatening, it's family.
By the time he's done, he heads towards his communicator to check the time, right when it beeps. A text, from Caroline, asking him to meet her in the holodeck. No, not asking him. Telling him she needs him. It's enough that he's out of their room in a heartbeat, leaving a puzzled wolf there on his own, as he heads towards the holodeck at full speed (such as it now is), the door sliding open for him. There's small smudges of paint on his face and arms - a little dark blue over his right brow and on his left forearm, an ochre near his jaw, some white by his right wrist - but he clearly could care less. Caroline needs him, that's all he knows.
