Penelope's goals was always, clearly, 100% straightforward to survive.
Even when she realized her crush on kalisto, she snapped out of it and did not entertain romantic thoughts afterwards (he also kinda destroyed her feelings tbh lol).
But with Eclis it was never about feelings.
You all have to realize they both are using each other to survive.
Sure, he may have developed an obsession towards her, but their dynamic started rotten from the beginning.
She can't be making hasty decisions to runaway when he's not 100%, girl is smart and knows she needs to watch her back.
AND isn't it weird how the game didn't give her a prompt like "Runaway event! Accept eclis and gain points of favour with him!"?
But nope, it was completely silent. Gave me very weird vibes.
Like running with him would've been BAD bad.
