She doesn't know the half of it, because now Michael's going to use that bathroom key to forge one for Shannon's office. "All you need to beat a tumbler lock is a little information and some stone-age tools," Michael VOs as he works on making a homemade copy of that key. "If you know the basic kind of key you need to spoof, take out a matching blank, file down the valleys to the central ledge, and you have a bump key. Apply torque, whack it with anything handy, and you're in." I know the show doesn't want to give out information that people could use to actually break the law, but maybe it would be better to not do it at all instead of pretending to with a VO that doesn't actually make any sense. Michael tests his bump key on a little lock he has handy, just like they did in the Stone Age. Fi enters, and Michael invites her along to the airport. He wants to "pay a visit to that front business Barry found." Fi complains, he snaps at her, and he finally leaves, saying he'll go alone. As if he's not better off doing it that way anyhow. They agree they'll have to discuss this out eventually. "Just not right now," Michael says. I agree; that sounds like something that can wait until the end tag.
