[CarlaConnor]

Corrie: Leannes less than happy when Peter defends Carla in the pub.
Corrie: Leanne catches Peter with Carla in the bistro.
Corrie: Peter turns his back on Carla for the sake of his marriage.

All of this airs in 2 weeks.

So obviously Peter and Carla are friends again at this point, but he turns his back on her for the sake of his marriage and urges frank to look after her so, I think when frank does what he does to Carla, Peter will blame himself for not being there for her. But before Frank hurts Carla I also think that Peter will actually have issues with Carla and Frank being together and become quite protective of her which could possibly lead to an affair like the rumours were saying?
