PilotLara ok, there's perhaps a bit of more genuine issue with Holly Trinity than the one i've mentioned earlier (as that one looks to be intentional, just with really clumsy implementation). Anyway:
tl;dr: it's perfectly possible to get Slut Holly into Holly Trinity, which the game clearly expects to be mutually exclusive, given the scripting in CH.13
details:
the minimal set of requirements to establish Holly Trinity is just:
Python:
lena_go_holly == 5
holly_ivy == False
ian_lena_dating == True
gillian_stop == True
lena_axel_fuck == False
ian_cuck == 0
That's all. Ian doesn't need to have romance with either Lena or Holly, Lena and Ian don't need to have _love flags for each other, Ian similarly doesn't need to have any feelings for Holly, and each and every one of them can sleep with anyone they want, other than Ivy fucking Holly.
This means we can have Holly who have fucked Mark and/or Robert. (but not Ivy) Then, come chapter 12b, this happens:
Python:
if holly_ivy or holly_guy > 1 or holly_robert:
$ holly_slut = True
But since
holly_slut
doesn't block the trinity, the game simply runs with this through the rest of Ch.12, and as a result we get lovey dovey freshly formed throuple cuddling at the beach. Then on next day Holly is sucking random cocks at the gloryhole, and Lena doesn't really think anything special of that. The only reason they don't just go back to lovey dovey cudding in Ch.13 is the fork between
holly_slut
or not that skips the second trinity date, but the actual trinity is still ongoing in the earnest. Which... well, doesn't really make much sense, when otherwise the game insists on only letting "pure" Ian and Lena to form the trinity because Holly is such a delicate, inexperienced soul she for sure couldn't handle having more sexually experienced partners.
meantime Holly: *cum burp*
