Rasputin pulled out of the drive, the car giving an odd thump as Rasputin ran something over. If he had bothered to look back, he could have found Seyrun's now significantly thinner and less alive familiar. Luckily for Seyrun, Rasputin didn't bother.

Rasputin doesn't have the skill to find Seyrun's familiar. As I specified before, it's laying at a distance that would require a skill more or less similar to hers to detect. Seyrun is actively trading precision for stealth, since she can't get more detailed info (like a small item on someone's hand, or whispering between two persons) from that far, but at least her familiars are as hard to detect as is possible (most likely perched on a tree a good distance from there, or atop some random house/building).

Furthermore, following the previous set of instructions the familiar will follow Lancer, because she is a more powerful source than Saber (as far as I'm aware he's the most powerful Servant in the whole war) and is leaving quite the trail because of his an Rasputin's carelessness.

I believe this is fair, not [@Unoedipal]?
