"Wait!" Strange quickly states, as he takes a few steps towards Childermass. The man's here so dammit, Strange is going to take advantage of that and actually talk to Childermass before he turns into shadows or turns back into a bird and resumes his normal pattern of ignoring him. "I don't know how far back you were eavesdropping, but I have some books that you might want to borrow back at my trailer. I'd be happy to lend them to you, if you wish."

Some of them were books that Strange had already read and enjoyed, a few were books that he desperately wanted to read but Norrell kept squirreled away in Hurtfew. And what's the point of working under a powerful faerie with the power to cross dimensions if you can't ask her to grab some books you've always wanted to read? Strange pauses for a moment, hemming and hawing before he starts speaking again (and straight up ignoring whatever Lambert's doing in the background, sorry bud). Because...might as well get this done.

"And I truly am sorry for my actions in Portland. I know that hardly erases what was done--that me was utterly heartless and needlessly cruel. But an apology is the least I can do to try and right that man's wrongs." He doesn't expect Childermass to forgive him. Hell, Strange isn't sure he'd forgive himself were he in Childermass's shoes. But he's no idea if the man's actually read the letter so he at least needs to say this here and now.
