An agent of a high profile athlete would be rich and famous.
Lexi's dad skips out on dinner with the family multiple times for work, something that I can't picture a former athlete doing, especially one who retired to spend time with family, but a sports agent buried in paperwork, I could.
I'm just wondering if party girl Emily had an intimate encounter with the star basketball player and that's why whenever everyone says MC looks like someone, nobody ever says Santi because they are shushed.
Well there's agent rich and famous and basketball star rich and famous, which is quite different IMO. Show me some pictures and ask me which one is LeBron, I could do it and I don't even follow basketball. Now ask me to point out LeBron's agent? I wouldn't have a clue and the same for most people.
Why I say this is when the MC, Erynn and Lexi are talking about having someone older "hire" Erynn to get close to Ethan. Lexi mentions how her dad would help, as he loves Erynn and Erynn says how "He's too famous" and Ethan would know him.
I think the main reason why Lexi's dad doesn't turn up to dinner was that Nyx wasn't ready to play that card yet.
If he did turn up at the restaurant and if I am right about his identity the MC would instantly recognise him and realise that he's Lexi and Layla's dad. If you are right and Santi is their father then we would see a reaction from Emily.
Either way that card would be played and no cliffhanger opportunity and no "shocked pikachu" MC moment, when he finally sees who Adrianna's husband and Lexi and Layla's father is.
