[There's no sneaking necessary for the professor that evening. He's one of the ones who put her here, after all, and the others are quite aware he's not likely to let her go wandering on her own. His own assurances at their doubtful looks help a lot, too. But he supposes she'll want to know about Major Alenko, and he wants to get another look at this special collar of hers.

So the nearest attendant unlocks the door for him, and he knocks politely. Even offers a slightly sheepish smile when he's let in.]

Good evening, Commander Shepard.
