I'm pretty sure Tom apologized for BCR before they broke up the first time, after some fighting and whatnot, and everything was fine. Then Mark got antsy when Tom was seemingly going to do some solo project and that caused more fighting, which lead to the first break up. I'm not sure Tom wanted to do the reunion at all, and seemed OK with touring and maybe a reunion record. I think he honestly felt bad that they broke up and wanted to keep the friendship alive considering one just almost died. You could tell Tom was never going to make Blink the priority in his music life.
The Tom firing Travis thing is kind of weird, but then again Travis was supposedly threatening his wife. If I did that, I'd be fired from my job honestly. Mark seemingly just let that one go by just fine, which is odd.
