For a moment or two. Look, I get that Ivy for you is a dream come true and so on... I get it because I think the same. From pure lust standpoint Ivy IS the Goddess. But the thing is, you think so because all the scenes you seen her in. She was smart, she was seductive, she took on the role of the corruptor and she even showed herself as someone you can at least partially rely on. That's all great things but, as it happens, none of this is known to Ian. Ingame for him she is just an extremely pretty face and Lena's friend. That's... cool and all, but he probably meets a couple beautiful girls like this every day. And yeah, it's nothing unusual to gush about them a little bit. That's not a sign that IanxIvy is in the works, sadly.
Both Ivy and Jess are back in the line among some others simply bcz of the fact the EK's focus is shifted from them to other non-important to story characters or cameo characters. Period!
If EK focus was on them (in Ian story) to begin with. Doesn't seems like it, to be honest. There were a lot of opportunities to include Ivy in Ian story during those 11 chapters in really meaningful matter. None taken and that's not a coincidence. Hell, EK basically said that she never considered Ivy as a factor in Ian story till now in the last Q&A. Of course now she will, because there was a question and that means that there is interest in that pairing, but I wouldn't bet on something more than a hook-up or two if I were you.
