I think Hayley will forgive Klaus when the enemy will harm their child, At least Klaus can protect Hope. (Jomo or Phoebe said) They'll forever be connected by Hope
But now Hayley's still angry at Klaus. Hayley want Klaus suffer as he did to her and of course she want to take Hope back.
Hayley will team up with the witches do something to Klaus.
I guess s3 ep1-9 They Fight for Custody Hope but after that there will be something make they restore the relationship. maybe It's another enemy come to harm Hope.
