I guess it's kind of odd that his inner monologue doesn't say what he was thinking, normally it's quite comprehensive when it comes to what he's thinking about. I might have guessed the 'Daddy' stuff, myself. Although I really have no idea what would be good for someone as broken as she is. Strong dominant man who is gentle with her? Going full dyke like Vanessa? Or is the stuff with Blake actually helping her? Who knows?
Yeah, I probably could've wrote this one better, but I tried to reflect how stupid this whole thing looks from Blake's perspective. Visiting a woman you care about just to be ordered to strip, and then get fisted on the table with no foreplay or affection whatsoever. There could be a thousand of reasons to tell her to fuck off after that, but I'm gonna let Blake choose if he wants to see Bree again, and since it's also a player's choice, I made this kinda ambiguous. Basically, Blake will find arguments both pro and against the decision you'll pick for him.
I suppose it fits with some of the other things we know about Blake. You'd expect someone as close as Suya would know who he is dating, but I guess just like he doesn't go to visit her very much he doesn't talk about her either. I can only imagine how Iris would react to that though if she found out that his roommate and closest friend doesn't even know they're dating. Or Vanessa. She only knows about Bree because she walked in on them.
She also knows about Liam (for same reason) and Samuel (because she was curious why the hell someone like Samuel would visit someone like Blake). If Blake is on Melinda's route, there's gonna be a special scene between Blake and Suya about all that stuff. Naturally, she's far from being happy. There is indeed tension between these two, mostly because Suya thinks that Melinda chooses to do absolutely nothing about the sorry state of the city, and instead just minding her own business. She will also going to think that Melinda is just using Blake for fun, and will get rid of him eventually. Basically, Suya is absolutely sure that she's the most important person in Blake's life, and will be heartbroken to learn otherwise.
As for Iris's reaction, that's a deliberate thing. Because Vanessa has no idea Iris is dating Blake either. They're like teenagers hiding their relationship from their much more mature guardians. Not because it's forbidden, but because they have no idea what to expect.
