Lily's instinct was telling her to stay away from Raven, a feeling she typically experienced around men. However, since Raven was a girl, Lily couldn't understand why she was feeling this way.
Lily's natural beauty has often attracted unwanted attention from boys and older men who try to take advantage of her, which is why she has developed a protective instinct that warns her to stay away from potential threats.
Unbeknownst to Lily, Raven is a master shape-shifter who is currently inhabiting a female body, preferring it because she finds it easier to shape-shift due to its flexibility.
But know Lily confused because she perceives Raven as female. What she doesn't realize is that her instincts are actually responding to Raven's true nature, which is male.
She brushed it off, thinking maybe it was because Raven's sense of fashion was a bit boyish, and tried to set her instincts aside.
Lily: _sighs_ Okay, let's focus on flying. I'm just really struggling with this.
Raven: _smiles_ Don't worry, I'm here to help. We'll take it slow.
Lily: _looks at Raven with a mix of confusion and unease_ You're really good at this, huh?
Raven: Yeah, I've had a lot of practice.
Lily: _tries to brush off the feeling_ I guess I just need to... _pauses, looking at Raven's outfit_ You know, your style is really... interesting.
Raven: _laughs_ Oh? What do you mean?
Lily: _tries to rationalize_ I mean, it's just a bit... boyish, I guess.
_internally_ That's why I'm feeling weird, it's just because of her style... right?
Raven: _smirks_ Maybe a little. I like to keep things practical.
Lily: _nods, trying to convince herself_ Yeah, that makes sense. _glances at Raven, still feeling uneasy.
