@Luna lu He has protected the psykers so Celestial Garden or whatever are definitely coming after him. Plus he has some platinum plate or something that they want.
And my comment was not focused on Cassian not doing anything. It was more focused on the fact that those girls are very deeply involved in the war like Moojin (her father or someone was killed), the new mystery girl (she's with the Garden) and the Pink haired girl (she's in danger because of her powers).
They wouldn't be spending time chasing after their love for Cassian or whatever. Even if they are teenagers, they have enough sense to know that this is NOT the time to be fighting for some random dude.
Moojin, for all she talks, about revenge seemingly isn't doing much to chase after it. It's a flaw in the character.
The pink haired girl doesn't realise how much in danger she is, Cassian isn't some bodyguard who will protect her 24/7 and come to her rescue like a Knight in shining armor.
The mystery girl, I don't even know what to say about her. We don't even know her real name. Cassian is being far too irrational bringing both the pink haired girl and the mystery girl into his house.
I just feel like the girls are just being used as a love plot device sort of characters and it's bad. They have so much more potential than just being 'Cassian's love interest'.
