So Tommy likely was going after Eddie, especially as they had 3 'dates' in 2 weeks and he definitely therefor caught Eddie's 'vibe''. But then he got no response from Eddie, and Buck surprised him with his positive response. So he probably felt, what the heck, lets go for Evan if Eddie isn't going to play along.
So it was supposed to be Tommy and Eddie, but flipped to Buck and Tommy. Does that mean Tim was planning to bring out both Eddie and Buck? That's sure how it reads to me. It also makes sense given the Catholic arc for Eddie, which was supposed be about him and Tommy and not him and Marisol. So confused. What are they going to do with the Catholic arc now? Are they building or breaking Eddie and Marisol? (I hope the latter)
