I'm plumping for a happy ending.
I think the gentle way that Neil spoke to Ryan after Catherine visited him in the shop was very effective.
So was the angry way that Ann told him her feelings on the matter.
I think Ryan knows enough not to go with the Wankertron. His mum killed herself because of TLR, Ryan is in no doubt now how Ann feels about what TLR did to her, and his Granny can't live with him if he's seeing TLR, so surely he must weigh it all up and make the right decision? Surely he's googled TLR's crimes?
I'm just worried about who else TLR hurts, and kind of hoping the Knesevicz's just kill him.
