The best present would be them breaking up and solo Josy route on DIK path
Nah, the best present would be DPC making a throuple path possible for those that want it and not making it unavoidably doomed to fail like the last one.
but why would her father go away? what did he go to his daughter's room for? a random raid that he'll repeat another random day?
it seems more logical to me to think that she is there because she already knows or suspects something (Josy is now officially her roommate, so it doesn't seem impossible that her father, who already has the room key, also has this information). going randomly to her daughter's room seems like a huge risk to me, if Maya had been in her room and woke up what would have happened? the father how he would explain his presence INSIDE the room.
if they don't find him there I hope there will be an explanation other than "because there is more drama"
Who's to say we're seeing this in sequence? Maybe the Dad has been waiting a while for Maya and he gives up waiting, and either goes to look elsewhere for her, like asking Derek, or goes home. As much as it would be good to have some sort of confrontation with him right now, having him not be there does make things more tense and puts you on edge. Imagine the start of Ep 7, the trio are back in the dorm building, Maya takes out her key to open the door, and when she opens it nobody is there. We the audience know he was there and he has a key, but they don't. It ramps up the tension because he could come back at any moment and they won't be prepared for it, and Maya will likely be caught with Josy or with Josy and the MC, which would be a huge moment.
I wouldn't put it passed DPC to potentially do this.
