Is it possible to meet Bailey at some point in time or it doesnt matter if you let her go? Can i remake her if i eat her when i reach the next evolution level or something?
Currently, Bailey status is unknown, in terms of her being revived or not. I would say your best bet is to eat her. Her memories will be stored up there for later vs letting her go to the Black Sea to possibly be trapped in the monster world.
I have a theory on how she'll be revived, if you eat. Since she's a partial Minyak, we just need to find a powerful one to store her memories inside. The only reason this would be needed is because Bailey's memories are based off of her being an Oil Zombie. She wouldn't be compatible with normal human bodies. The other alternative part requires some breeding by the MC with Minyaks to make her way more powerful but leads to some incest. My detailed post is here still on that topic, somewhere.
Anyway, this update made my theory even more possible since the MC was indeed able to give the stored memories of Jake to Mia, if you killed him. Some thought it couldn't happen but this update proved that he indeed could share memories with others. Even faster than I thought he would be able, if I'm being honest. So I'm of the opinion that eating her and saving her memories is the best course of action.
I'm not sure what WW intends to do with Bailey but that's the right thing to do, in my opinion. Letting her go seems like it's going to lead to her getting crushed by any stronger monster or HERO agent she comes across. Even if that doesn't happen, she was made for breeding so she'll get ravaged by countless monsters, if she reached her destination. Seems safer to just eat her.
