After last week's mind-boggling season premiere, the residents of Chester's Mill are right back where they started: under that dome. On Thursday's episode, Junior (Alexander Koch) gets a harsh reality check from - who else? - his father, after bloodying his knuckles in an attempt to punch his way out from under the dome. In the clip above, exclusive to TVGuide.com, Big Jim and Junior seem like they're working towards a reconciliation - but predictably, the conversation ends with a fist to the face.
