Geoff is not going to be the father of Jill.
1. right Jill was not at the party. But who does Jill go to parties with? Bianca. Jill canceled on Bianca because she's taking care of Cathy with Isabella. Geoff is looking for Bianca because he thought so his daughter would be there with Jill.
2. Gordon and Christian realize so Geoff had one too many. But Jill's father started drinking after Lana died. So Jill's dad is an alcoholic and they don't get drunk very fast because they are trained. You're actually proving with that so he's not Jill's father.
3. of course he is sitting next to Amelia. How did Jill and Bianca meet? She had to go to the Royce with her parents. Who is at the performance? Bianca. Geoff sits right behind his daughter and next to him Amelia, a family friend, whom he accompanies because Jill's father is drunk again.
Most importantly, why is Geoff helping the MC at the preps party twice? Once with Christian and Gordon and the second time Geoff draws the attention of these two guys to distract from the MC.
