2. Adama and Tigh (Battlestar Galactica)
Few friends are as strong as old friends, and these two have been through the ringer. They've fought a Cylon war together, saved each other's asses countless times, and lead the human race out of utter extinction and to a new home, and while they did it, they were always keeping each other in check. Even when they fought (and what a fight), they finished up by drinking together. Despite everything, despite Tigh turning out to be one of the fabled Final Five and a cylon, his and Adama's friendship endured, both being the respective father figures of their race. When Adama takes a bullet in an assassination attempt at the end f season one, Tigh is thrust into a position of leadership that he doesn't want and has no idea what to do with. As the situation escalates from one horrible disaster to another, Tigh soon finds himself imposing martial law. He goes to Adama's bedside and practically begs his old pal and senior officer to wake up to fix the mess he's made. When Adama does return, that exactly what he does. The great thing about their friendship is that Saul has almost zero desire to be a number one, and works far better as a number two. Similarly, Adama is a clear leader, and could never be much of a follower, as his conflict with Admiral Cain proved. Only when they're split up does Tigh come into his own as the leader of the resistance on New Caprica, resorting to extreme acts of terrorism in order to fight the cylons. Meanwhile Adama bides his time and waits for the best opportunity to sweep in and rescue the humans living on the dystopian colony. Through their combined coordinated efforts, they manage to bring the entire human race out of cylon occupation once again. Few partnerships in TV can rival that of Bill and Saul.
Best bromance moment: Tigh: The civvies are complaining about the food shortage. Adama: I hear they're still eating paper. Is that true? Tigh: No. Paper shortage. Silence. Laughter, laughter, laughter.
