Lambert asking if he can help is damn confusing. Still, he's not going to look a gift horse in the mouth. If Lambert wants to try and help, Strange will gladly take advantage of that.

"Actually, you can help. Stand still, please." And Strange is just assuming Lambert's going to do so, because he's a bossy asshole! He takes a few steps back before activating his third eye: the burn scars on Strange's forehead, hand, and forearm light up with flames. While he does so, he scrutinizes Lambert, sizing him up in a way that's far too critical.

"Hmm. How odd. Obviously I'm touched by the magic of the Silver Mirror, but there's a large amount of it lingering around you as well." He'll need to run tests. Ooh, he'll need to come up with tests and then run tests. Just the thought of so much magical nerdery is enough to make him smile a little.
