So....yeah, just my opinion here but.....
I get this is a slow burn with Emily, however, there are two other females in the house.
1. Ash still acting like a bitch at this point and the MC having sub par comebacks is to much. We already learned that she is tough on the outside but vulnerable on the inside. The MC should be man enough by now...proven by the WT with how he is with Samantha, to call her out on her bull shit and have fun with her.
2. Samantha, I could see being a slow burn given the fact she is responsible for these "kids". Just not as slow as Em. It just seems at some point there has to be a "fuck it" line for her. The MC saved her, then the scene in the MC's room at night. Then this episode and the look on her face leaving the bathroom.
I get that Emily, by her stats alone is the main LI, however, more could be done with Ash and Samantha. Again this is just an opinion.
