Another thing about Buck is how he is surprised Eddie and Tommy don't talk anymore.
Like Buck, sir, did you forget how you looked when you showed up at Eddie's doorstep in shock and in misery over Tommy breaking up with you? Did you forget Eddie took your phone when you entertained the idea of calling/texting Tommy? Eddie, too, was a recipient of your homemade baked goods madness cuz of how Tommy dumped you. Ofc bestie Eddie would never still be in contact with Tommy cuz he saw how hurt you were Buck, you were hurting bad Buck.
Which makes the infamous jealous Buck episode even better because Buck thought Eddie and Tommy were best buddy buddy pals playing basketball and going to MMA fights together, felt like he was getting replaced with them having more in common as military vets and so on, only to find out through Tommy that Eddie chose Buck no questions asked. Eddie chose Buck and didn't even tell Buck that he doesn't talk to Tommy anymore cuz Tommy is unimportant now, especially since he hurt Buck's feelings.
