Willow feels like a sex toy instead of a companion.
If you've met her and don't like her I wouldn't expect that to change over time no matter what she does during gameplay. I usually decide whether I like a companion or not within the first five minutes. And, no, she isn't designed to be a sex toy, but I've found that her casual, sexual empowerment is confusing to a lot of players. I'd never write/release a girl companion like her again.
My question is how is willow's character?
Willow is an anti-NV character. She was written to be out-of-sync with everyone else in the game and to offer something different. She's the optimistic character in a sea of depressed ones. Her main trait is that she's devoted to the Courier; as friend or lover. It doesn't matter to her which it is. The relationship between the player and Willow grows over time, and is reflected through dialogue, which is different depending on what you do with her and if you are just friends or romance her, but primarily she's simply a devoted companion that offers her impressions about stuff and keeps you company. That's what I designed her to be.
Thank you that is the answer I needed. Apologies for any offense that I created, I just have high standards when it comes to modded characters and quest lines and every youtube video I have watched of Willow has portrayed her as an overly sexual object and I needed clear answers on if there was something missing. Have a good day everyone and keep modding.
