Maddie does her best to keep from getting caught watching - although she's certain that he's not going to do anything overtly suspicious, it was still her job to be careful and thorough, and if he looks up, if they make eye contact, it's not much of a stretch for her to offer the smallest, most embarrassed little smile, and to look away under the guise that she'd simply been ... admiring a rather attractive person.

Because despite the things that he's suspected of doing, he is that. Attractive. Very, very attractive. She is flustered, and she mentally berates herself for it, because, damn it, she's got a job to do. There was no time for anything else.

Maddie does much the same, but only to be sure that she can stand close by. She can't be too obvious in the way that she's tailing him, lest he catch on to what her real agenda is. This time, at least she can stay on his tail long enough to let her team know where he exits the train. It's a start.
