Lan Wangji is not the best at casual conversation on most days. But there are still things that are bothering him from the last few weeks. So as he starts to place things in the bag he considers his options in what could be asked of this man.

"I woke up in a suitcase."

That...is probably not a very good way to put things but it is the truth. Waking up in the luggage car was unpleasant and realizing he had lost time while in there was equally so.
