Of all the people that Kanan expected to sense today -- and most of that was being prepared to feel strangers -- Cassian was not quite last on the list, but it was close.

It takes Kanan a moment to gather himself not to react, exhaling and pulling another book off the shelf to peruse in his own time.

Of course, then he looks up over the edge of said open book, gaze unerringly meeting Cassian's for a second, and then he looks back down again. A momentary shrug, an impatient sigh, and he returns the book to the shelf before ambling in Hera's general direction.

He hates to interrupt her fascination with the paper books, but the mission always comes first.
