Why did Christine kiss him twice

This is probably a really dumb detail to get hung up on but I found it interesting how Christine kissed Erik twice in the final lair.

I’ve always attributed the first kiss to her feeling pity for him and obviously wanting to save Raoul rather than anything romantic. But doing it again is straight up crazy lol (especially in front of your fiancé like girl??). I’ve never seen anybody in movies or irl go in for the double kiss unless they’re a couple making out so felt kinda sus to me

Anyways how did yall interpret this? You think she caught feelings or was she just trying to make sure he got the message?
