Watch out for spoilers! I recommend you play to the update's end first and then come back here to see if you missed anything.
Smiley, Tail and Mermedon.
Requirements.
Go with them to the hot springs. Events will then unfold on their own.
Notes.
This sequence of scenes has two beginnings: drunk and sober.
Drunk is only the beginning. In this option, Selene is drunk enough to start doing stupid things, but not enough to not understand what is happening and realize it at the key moment. The moment when the adrenaline kicks in, she sobers up almost instantly.
To refuse in the drunk option, you will need to pass a Willpower check.
The sober version assumes consent or refusal solely at the player's discretion.
In case of refusal (not letting Smiley do his thing), the entire sequence will be canceled, but a second opportunity will appear.
In case of refusal to continue (after Smiley has done his thing), the alternative lewd sequence is canceled, and Selene returns to camp.
This sequence includes Selene's first, ahem, anal experience.
The scene also includes a virgin variation.
Only Smiley.
Requirement.
Selene must not let Smiley fuck her at the hot springs. Instead, she will get angry, say nasty things to him, and run away. Smiley will run after her with apologies.
Notes.
This is an alternative to the hot springs orgy. All scenes feature only one character: Smiley.
There are two opening scenes for this sequence (three, actually).
The first possible opening is a “nutty” one. For this, Selene must not be a virgin. After Smiley catches up with Selene and talks to her, turn him down. And when he's about to leave, say “weakling” at his back.
The second possible opening is not to reject Smiley when he asks permission to kiss Selene. You'll figure out the rest yourself. The virgin variation will automatically be enabled on this branch if Selene is... yeah, still a virgin.
All other scenes play out on their own. The connecting scene takes place at the waterfalls. And in the finale, there is a fork between two different scenes on the rug by the hot springs, next to the sleeping Tail and Mermedon.
Chat.
Requirements.
Sleep with him in the previous update. This is the only and main requirement for all scenes with him in this episode.
Notes.
The scene in the bushes after breakfast with tough jerky meat is available if you go after him with the “we need to talk” thing. The presence or absence of this scene changes the difficulty of the Mind check in the next scene with him.
The scene where Chat comes to Selene in the middle of the night on the next day. Subsequent events may affect the ending of the episode. In either case, whether Selene (for whatever reason) lets Chat finish what he started, or makes a fuss and interrupts the scene, leading to a fight between Yuturna and Chat.
The last scene with Chat will be on the last night at the camp. He will come to Selene again. But only if Selene did not refuse him before (there was no fight with Yuturna).
Greeny.
Requirements.
Not be a virgin. Give Mermedon a reason to believe that Selene is suitable for the task he asks her to do. To achieve this, one (or more) of the following conditions must be fulfilled:
1. Sleep with Chat (previous episode)
2. Participate in an orgy with Smiley, Tail, and Mermedon.
3. Sleep with Smiley (alternative to the orgy)
4. Sleep with Smiley (start of the orgy), but return to camp immediately afterwards (do not continue the orgy).
Notes.
After this scene, Greeny may or may not become more confident. It all depends on Selene's actions. And yes, she can ruin everything at the very end, even if she did everything else right.
