Maybe the ending isn’t Catherine dying, but alienating her family and ending up alone (perhaps having a close friendship with Alison). I don’t agree with going behind Catherine’s back but I can see why Claire is frustrated. Catherine is so blinded by the trauma of Becky’s death (not her fault) that she cannot think rationally when it comes to Ryan. It’s clear Claire doesn’t think TLR is an angel or anything, she acknowledges he should never get out of prison, but I think she feels closure to the situation would be for Ryan to know TLR for himself, and hopefully be at peace with his relationship with his dad.
Catherine prefers to bury her head in the sand, and has spent years biting Ryan’s head off at any mention of TLR. It’s obvious why Ryan went to Neil and Claire for help.
It was awful of Catherine not to tell Ryan the truth, he’s not thick.
I think Claire wants everything out in the open with the Becky situation, she wants everybody to have closure and move on. But then Becky isn’t Claire’s daughter, she’s Catherine’s, and Catherine will never be able to have the idealistic closure that Claire wants.
