Agreed. Not only does it provide the only explanation given for all his 'break them up' shenanigans, once we were given the reason they fell into the background. But also, didn't his whole thing with Nolan come about because Nolan figured out about his sugar daddy? I believe him when he says his sexuality is largely instrumental, but I never got the impression his relationship with Ashley was an exception to that rule. Tyler doesn't really know how to deal with having non-instrumental feelings for Daniel, and takes it out on both Daniel and Emily.
