These are related to chronology of events, and are progressively harder to unlock as you move further into the game (and get quicker relationship progressions because of titles).
They're both versions of Marla's second plant discussion with Lani (Planty Jr) and trigger if Lani has started visiting Liam in the tent, but not progressed very far (the Dungeon Tent replaces this progression, so you'll need to turn it off in the tent settings).
Exact progression:
- Progress Marla to roughly before the second plant scene.
- Party with Lani (and turn off the dungeon tent).
- Progress Lani to tent scene 3, 4, or 5 (scenes before the night watch conversations).
- Progress Marla further and trigger the second plant scene.
- The scenes will trigger during the plant scene.
Break point:
- Which scene you get between the two is determined by whether or not Marla knows about Lani's curse.
