As long as he can, Strange just holds tight onto Lambert's wrist, as if doing so will keep Lambert from going away and actually force him to stay put and have this conversation.

A brief look of exasperation flashes across Strange's face at Lambert's entirely unhelpful remark. Strange knows what he wants from Lambert: he wants to be trusted, wants to be included, and wants his friend back. How the hell is it so hard for Lambert to decide what he wants from Strange?

"But what I want involves you! I'm not an idiot, I know Ignatius won't be around forever." He's got a Court to go back to. He's got a life and a cause to go back to, just as Strange and Childermass do. The fact that he stayed on after recovering his Heart in Shabon is intensely admirable and yet another reason why Strange just absolutely loves this guy, but now that he has his Heart, he's going to leave at some point. And Strange is certain about that because that's what he'd do if he was in Ignatius' place.
