You`re making some good observations and than some bad ones that`s why your point is not coming across.
Why this sad,shy look?Because Maya has self awarness and conscience,she knows she fucked up and she feels guilty about it.
That`s the same reason why she cries here.What she did wasn`t cool and she does take the blame for it.
You are right,she knows the HoT tasks are sexual in nature and she goes with it,she tries to go with it on her terms,nontheless she does.
She has no clue,however about the prostitution,none,even when Quinn makes it bluntly obvious - "Loose lips sink ships But loose hips get tips" - Maya still didn`t get the hint.She`s oblivious as of how this tuition thing works.I don`t think she will be on board with it once she understands the deal.
The leaving dorm thing,it`s consistent with MC`s character to just leave,that`s what he does with Troy,no discussion,no attempt to understand he just leaves.
Look at their facial expressions,neither of them wanted MC to learn about their romance in this way,both of them had plenty of time and opportunities to let him know but they were waiting for sign from the heavens that it`s the right time.With Josy she at least did told him she is in a relationship.
I think it`s even higher than 50-50 after ep 3,the reason being,restaurant has somewhat became it`s own path,you have to sacrifice other scenes and the relationship points associated,to get the scene with Quinn and Riona.So if it requires special choices to be made it has to lead somwhere right?Please?
