In honor of ''Bones'' 100th, we've compiled PopWatchers' best-loved glimpses into characters' pasts, from ''Lost'' and ''Friends'' to ''Will and Grace'' and ''The Simpsons''
''During a boxing match where Starbuck and Apollo are beating the crap out of each other, we get to see them in love for a brief moment on New Caprica. Then Starbuck, of course, gets scared, runs back to Anders, and fraks up any chance of her happiness. It's not 100 percent flashback episode, but seeing Lee profess his love for her for all the gods to hear packs a big punch.'' Anne Marie
''One of the eps that illustrates perfectly the power of that show: with none of its CGI battles, no spaceships, no apocalyptic stakes, BSG can deliver absolutely captivating TV with just a handful of beautifully flawed characters hitting each other for an hour, to a heart-wrenching, hypnotic score.'' Ted
