Saverine and Jeb Saga

The Saverine and Jeb saga continues. I wish I knew why Jeb wanted to chase Saverine so much. I do not understand what that is about. I will say, on this particular morning, Saverine was on her own away from the rest of the horses and away from the hay bale. For whatever reason, Jeb ran over there and chased her back to where the rest of the horses were and the hay bale. The thing is, once he got her over there, he did not stop chasing her and Takua had to step in and get Jeb away from her. So, one minute he seems to be bullying her and then another minute it looks like he is trying to help her. I just do not have a clue, but it continues on.
