Yes, that's a tough one. I think it's more empathy from her side, given that she once fell in love with Hendrix (or at least that's implied). I guess she wants to save him from that pain, especially as she'll be the one experiencing a stranger falling in love with her. She can only ever know him for a matter of hours or days, whereas Cage has known her (or at least been around her) for many possible lifetimes.
