The big man almost barreled into L, who flinched, but was otherwise quiet. There was nothing to do but observe the interaction that unfolded.

When she issued the invitation, however, L aimed a quizzical, appraising glance at Lana. Are you sure about this?

The new arrival seemed brash and unsubtle, but she seemed to know him, and if she was asking him to come along and protect the two of them, she most likely trusted him to have her back. L didn't know that he would trust the man to do the same for him--the man seemed as if he would probably gravitate towards helping Lana, if he was forced to choose--but as long as he didn't actively hurt either of them, it would probably be better than nothing. L preferred not to travel at night with someone he hadn't already evaluated during the day, but just now, he and Lana needed help, and he couldn't afford to be selective past "Probably won't kill me": it was a matter of balancing the tension between that and "Will help me if I'm attacked." At the moment, they didn't have many other options.

What she'd said about the outfit caused him to wonder... never mind. It wasn't important at the moment, and it might make an interesting topic of conversation for later, to pass the time on the long, dull slog.
