I didn't want to repeat SearingFive - architect or a civil engineer. Or something like that, I didn't recall the exact original line, either.
Trying to hit on anything that moves is also something that doesn't paint him in a good light, no matter how open he is about it. I wonder if he was just as open to Holly about not seeing her as anything but a random hookup without any value beyond that, as he was to Lena when she called him out on it? It's not a positive quality either way.
The way he got introduced with both Holly and Lena was very casual, so I don't blame him for just going with the flow and Ivy's intentions. You can only see it as bad if you are as needy as Louise and demand a fully committed relationship after the first fuck.
To the original point, none of men are something I want to be and for that matter, none of the women are someones I'd like to hook up with, since they are intentionally and by design for drama. Hence if I had to chose one, I take some random like Mark and like Eli, because they aren't fleshed out properly with flaws. I suppose I could say "no one", but that's a lazy answer.
