The reason Buck was so.. hurt by Tommy calling Eddie competition is because he was insinuating that their friendship, which is something so important and real to Buck for the first time in his life was something dirty. That his relationship with Eddie which he views as platonic is comparable to a cheap affair and it demons their bond to something not as strong and long lasting.
He was upset and said ‘okay even if I was in love with him I wouldn’t need to sleep with him’ basically, because he thinks Tommy views him as easy, and would go with Eddie sexually/romantically if they opportunity arrises.
Would he? We don’t know, Tommy doesn’t know and Buck doesn’t know. The important part is he made Buck feel wrong and like a cheater for having a friend and that’s why he snapped the way he did.
He isn’t Buck 1.0 anymore and Buck loves like he’s never had the chance to love before— because he hasn’t and being on the receiving and giving end of true, unfiltered love is everything to him.
