Yea sure. But it seems the discussion here presupposes that Lena will be returning to her parents' house. Was it ever confirmed by Eva or was it just teased at the end of ch 8?
I'm just saying what if Lena doesn't even return home? Maybe it's just a cliffhanger?

Take the end of ch 7 for example. Ian gets caught fking Cindy. Then ch 8 begins but we dont see the immediate aftermath of his getting caught by Jeremy and Ivy.
I don’t think Eva has confirmed it, no.
It's true that the immediate aftermath of a cliffhanger like the one in ch. 7 isn't always shown, but I don't think that's completely comparable to the end of ch. 8. In ch. 7 the main event – Ian and Cindy in the back alley – had already played out. The consequences from it, and from Jeremy and Ivy catching them, are bound to be shown at some point, independent of how that tense meeting between the four of them played out.
In the cliffhanger of ch. 8, the only thing that's happened is the phone call where Lena's dad tells her she needs to come home. The fact that Lena's mother's health problems are introduced into the story, needs to have some kind of consequences for the story as a whole. It
could of course affect the story without Lena going home – it could affect her financial problems, for example, thus making her more reliant on the persons she can make money from. But if I remember correctly, Lena's dad said "We need you to come home". I don't think Eva would have written the dialogue like that if if wasn't to indicate that she'll actually do so in the coming chapter.
