MC: "S-she's back? Why?"
MC: "Uh... I think..." (Form this statement into a sentence. Remember, the MC hasn't had any contact with Zoey in over half a year. So he can't imagine or know (screw English and the multiple meanings of single words) what made Zoey come back. So he found out something about Zoey, but not from Zoey directly).
MC: "Give her my new number." (He obviously wants to talk to Zoey, although he even changed his phone number after the Rooster Cluck. Yes, he changed his phone number. Zoey could no longer reach the MC. But in EP7, the MC tells Josy that he has the same phone number on his new cell phone. Ergo, he changed his phone number after the Rooster Cluck).
MC: "Hey..."
MC: "Is she ok?" (The MC asks his father if she is okay. Zoey still means something to the MC).
MC: "I understand." (I don't know because I can't know what Neil said).
I noticed something else. In the EP3 review of Zoey, we also learn that Zoey had a girlfriend with a brother and the brother always got the alcohol.
Josy and Tommy: (Possible, but not confirmed.)
Maya and Derek: (Possible, but not confirmed.)
Sage and Tybalt: (Possible, but not confirmed.)
Tommy and Derek are resourceful. They could get the alcohol, I'm sure.
Tybalt had a bar built at the Preps mansion a year ago after an incident at a local bar. Ergo, Tybalt had alcohol in hand a year earlier.
Who is present at Burke's? Josy, Maya, Sage. Oops. The three girls all have brothers who get alcohol, right?
Didn't Sage say in EP8 that the MC was supposed to have met a girl who left a year ago? Did this girl maybe go to San Diego? Sage really wanted to go to the MC's bathroom.
Doesn't sound like a conspiracy theory to me. More like a possible story development. Maybe, maybe not.
