Lex had heard the sound of wheels against the pavement and in a split second had decided it wasn't a threat. Auror training taught you how to do that and it kept you from being overly jittery when you were on the street. That being said, constant vigilance still needed to be exercised. There was someone approaching on wheels and Alexa was acutely aware of their position at all times.

The sudden halt in the rhythmic pattern of rolling wheels followed by quickened footsteps however got her turning ever so slightly. It only took one glance for her to halt her own steps, obviously taken by pleasant surprise.

Lex pulled a face at his question, now reminded of how she spent the greater portion of the night before. "If I never see my desk again it'll be too soon. There's only so much documenting I can do before I start committing the crimes myself." It's why at somewhere around perhaps 2 am, she'd opted to leave the office in favour of anything else.

"I see you've gotten better at your stops too." Her features split into a teasing grin as she made a light jab at the first time they'd met. That....had been an interesting train ride.
