No clue. [Even if he can't see Lancer's face, her posture looks quite closed off.] Mind, this is an unusual move for Rider's Master. He has his reasons for keeping out of sight, and there are too few trees in this territory to take advantage of. More importantly, I think he'd rather not alert his former boss that he's in the area.

[Woodland is doubly convenient in that there are no security cameras around, rendering the Eyes of God useless.]

If I were to guess: this might be Rider's own initiative, and he's also picked a terrible spot. The Port Mafia's docks are more suitable for his regular vessel, should that be tied to his Noble Phantasm.

[Sorry not sorry, Steinbeck. It's not a leak if just any observer can draw their own conclusions based on your Servant's attire.

The closer Lancer is to boiling point, however, Casturia will straighten and peer down at the two intently, summoning her staff in clutched hands.]

She is the one suspected of killing that civilian at the train station, yes?

Master, please give me your orders.

[Not to attack necessarily, but she will shield any innocent bystanders if a fight breaks out.]
