There's a suit of Chula armor discreetly stalking Suzie. Has been for a while, now.

It tracked her as she went to talk to Sam, then followed her progress up to Gwen's office, then positioned itself in the lobby, passive-scanning and mapping out potential routes.

Once again, there's nothing it can do. Can't accompany her without both endangering her infiltration and changing the course of the timeline. Can't prevent her from going without... well, doing both of the above, to a much greater extent. So what exactly it's stalking her for is an open question.

But, well, there it is.
