"Aren't you staying with the Ringmaster?" And a whole bunch of other people, yeah, Lambert's seen sorority cabin. "Seems rude not to share." He can guess why Strange is a little bit embarrassed about lighting up with his boss -- which Lambert doesn't apparently count as, but that's not surprising either.

Still grinning like he can't quite believe Strange is, of all people, the one being responsible (fiscally, anyway; as the magician's enthusiasm about hallucinogens clearly points to, the newfound responsibility isn't equality distributed) Lambert goes ahead and takes the marginally larger share of the purchase, letting the caravan worker mark it against his total credit balance. It doesn't take long until Childermass's present is all wrapped up, and after that, once Strange has made whatever other purchases he intends, it's back to Lambert's cabin they go.

"Don't smoke near the beakers," Lambert warns, as they shoulder their way back in. "I don't want you knocking anything over." The air has cleared of the noxious fumes before and it's chilly in here, what with the windows open, but considering Strange is about to stink it up again, that's probably for the best.
