This episode took a step back from the "let's divide the camp of heroes" arc and dealt primarily with the messy Petrelli family and its tale of three sons. Arthur Petrelli has already proven to be quite a baddie, but tonight, his game got mental, pitting his sons against one another and their mother. Papa Petrelli also brought Mohinder into the fold while Daphne was sent on a disturbing mission, Claire found comfort from an unexpected acquaintance and Hiro and Ando chose their path ... or had a path chosen for them.
Since the recap is tardy (and you guys are already off to a healthy discussion) I will try to be brief (though so much happened!)
