If they are just trying to mark Datu and Saul to basically say "Stay Away" or "Leave us Alone" or whatever..... Then I don't understand why they would need to bite them as well???

Seems to me that Randy bites them, and then scratches something on them......

So why not just scratch them and leave them alone??? why the bite as well???

Also, what makes Randy so special that his bite doesn't immediately turn someone???


Datu hung on for a while and then eventually turned anyways!!! Is that Saul's fate??? Or is there something that makes Saul and Tanya different.....
