The Skiff Crew and the Infiltration of the Fleet

There's a lot pointing to potential spice. A lot of them who are supposedly sick and wounded get ferried to the fleet, which would be a perfect cover story for an infiltration. The other thing I can't shake with this group is like, how did Gideon let them live unless they're his spies? Because the tie interceptor, we see all the tie interceptors in the base, we hear Gideon order them into action. It's very clear that these are the ships that pursued Bo and Din after they left Mandalorian episode two.
