Not Fade Away
After telling his gang to go do the last thing they want before they'll turn to the fight of their lives, which they would probably not survive, Angel follows his own advice and goes to see Connor. They meet up in a coffee shop, and talk a little. Angel tells him about Nina and Connor makes werewolf jokes Angel doesn't get. Connor tells Angel he knows everything, he knows Angel is his father and he's also come to terms with everything (there is a distinct change from the Connor that not so long ago refused to so much as discuss the subject). He is grateful for what Angel has done and he understands everything better now, but he doesn't want to make a thing out of it. Angel agrees and they continue to talk. Their meeting is closure, it's nice. Could have been perfect if it hadn't been the last thing Angel's about to do…
The next time they meet is when Connor appears in the middle of Angel's fight with Hamilton and literally saves Angel's life ("You drop by for a cop of coffee and the world's not ending? Please!"). The fight is nasty and too long, but finally, Hamilton is dead and the Wolfram&Hart building is falling apart. Angel urges Connor to go home, that this is his fight, but Connor refuses, saying they would destroy him and he needs help. Angel assures him they can't destroy him so long as Connor is alive.
Angel: Go home... now.
Connor: They'll destroy you.
Angel: As long as you're OK, they can't. Go.
