Not really, no. The only reason you wouldn't be seeing these additional lines is if the conditions for them aren't met, but this would require the relevant flags (open relationship, Lena/Ian relationship status etc) to get somehow reset.I have one suspicion: Is Lena aware that Ian fucked Cindy in your playthrough ? In my playthrough she is, and she is wondering whether he is still cheating on her. Might this be the reason why I do not get the threesome idea with Eli ?
You could probably check it for yourself, if you enable Renpy console. (here is info how to do it, e.g.:
You must be registered to see the links
) You could then type the name of given variable and see its state.
