you got me all confused man lol.
Here is my path:
In the last episode on the open relationship path, after Lena has sex with Emma, she texts Ian a photo of them together, Ian can confirm a threesome with both of them there, later in that chat Lena asks Ian if she can have sex with Ivy on the trip, to which Ian has 3 options.
Yes but ask for a threesome
Yes
No
I chose the first threesome option. But the episode ends sometime after that chat.
Will the dialogues you posted just above between Lena & Ivy appear on this path? I said logic fail coz Ian asked Lena for a threesome with Ivy to which she agrees, and later gets angry at Ivy when Ian was flirting with her? Does not make any sense at all.
