All I can gather is that these "
others" are female.
Pippin (spelling?) sounds like a nickname for a girl but where
Scratch was taking her...I have no clue. The one that they "still have", I believe this one to be a straggler they found during their search for the runaways. The one that hasn't responded? Well I answered that before...
As far as them making a deal with The One? I don't think so. I mean, it's plausible but Scratch doesn't trust easy. I think they are just trying to gather up their numbers since they lost so many during the war with
the tower. They are planning something and I think
Lizzy saw a piece to that plan.
