The Clu who appears in his doorway is very much the opposite of the one who appeared in the same place back on the Moira: quiet, polite, asking patiently to be let in. Alan isn’t sure whether he should be more or less alarmed—probably the former, given the circumstances.

He watches Clu in silence for a moment. He would expect Clu to be furious if he already knew Alan had his disk, but he sees no anger in the admin’s expression. Instead, the program looks almost funereal. Perhaps he really doesn’t know where his disk is.

If that’s the case, Alan has a monumental decision to make in not a lot of time.

In the interest of buying more, playing along seems to be the best option. Alan says nothing, not quite trusting his own words, only opens the door wider and steps aside. He's all too aware he could be making a very big mistake—but he hasn’t shaken that feeling since Quorra appeared at his door with someone else’s brain in her bag.

And if he's going to be holding someone’s life in his hands, he would at least hear what he has to say first.
