I think the case could definitely be made that removing that condom, without her consent, aka stealthing, was a form of rape. I believe it HAS been argued, legally, tho I may be wrong about that. Zain is shady AF, and I don't believe for a second he thought it was okay with her. I hate that she accepted it so readily and is still feeling flirty with him. I think that may change. He also had contempt for her writing success, and feels he's a better, more deserving writer. It was a complete power play on his part.
I admire how realistic this show is in dealing with Arabella's need for constant company, and also in how quickly she wants to reassert her own sexual agency. At first, the hookup with Zain kind of baffled me; they didn't seem at all into each other, there didn't seem to be any actual attraction on either part, and the sex, creepy stealthing aside, looked merely serviceable, something to get over with. But I also recalled, having gone thru a similar--or anyway, somewhat adjacent-- situation as Arabella back when I was 19, that throwing yourself back into sexual situations where YOU feel in control is a common defense mechanism. It's heartbreaking that the first time she does this, she's met with more sexual betrayal by a predator who looks like a nice guy but definitely is not.
I really also didn't get what was going on with Kwame and his new friend, who seemed into him, but hesitant, and despite what he said, a little scared. I'm not sure I get why Kwame immediately thought "threesome with a stranger is a good way to ease this guy into things!" Was it strictly logistics, as they had no where else to go? I'm also not entirely clear on what happened with the Grindr hookup guy...did he actually rape him, was there penetration, or did he just get himself off using Kwame as a sex toy? Either way is heinous, indefensible, and an assault; I'm just unclear on the details.
So really, with Terry's dubious threesome that she believed was consensual til she realized she'd been set up by the two guys...she, Arabella and Kwame have all experienced different levels of deceit and assault regarding consent and their own sexual agency. This show is brilliant, and so, so hard to watch.
