There is something to be said for being a night owl. Jacob has always been nocturnal, to some degree, because the nature of his work has demanded it. He's used to dozing in the warm space between a cluster of chimneys or tumbling into the sheets fully clothed at dawn and sleeping until lunch. It's worked, even if Evie has nothing good to say about it.

That's why now, in the middle of the night, he's just coming back. Not from anything interesting, just taking a turn out on the rooftops. This is why he enters the room via the window, and not the door. He left it slightly ajar so he could get back in that way, although a blade through the catch would have done the same job.

He's not expecting the other occupant of the room to be in- why should he? There are lots of fun things to do at night in this city, ones that don't involve climbing through windows. Most of them don't involve clothes. Hellboy seems the adventurous sort, from the little Jacob knows of him. Adventurous enough to let a perfect stranger get him off in a public thoroughfare anyway.

The memory has him grinning as he shuts the window behind him with a faint click.
