It suddenly dawned on me that the relationship between Alessa and Sal can be abridged as so.
Sal: I'm a freak of nature who can switch sex, and I like to shoot things.
Alessa: I'm an emotionally repressed woman who secretly wants to kill everyone. Wanna go out?
Sal: No, now fuck off, I'm busy shooting things.
*****
Alessa: I am very angry at you, and I'm going to torture you.
Sal: Even though you're on Asgard's side, and are my mortal enemy; I feel a strange sensation of love. I'm also going to bug the shit out of you, even though you seem to hate my guts.
Alessa: Sorry, what? I was too busy torturing you.
****
Blythe: I am a blind girl who is concerned for you.
Alessa: Even though he is very evil, and even though he hurt you; I'm in love with Sal.
Blythe: ...yeah, okay you're on your own here.
****
Alessa: I am very angry, and I'm going to destroy things with my powers.
Sal: Even though we are mortal enemies; I will invite you to my secret hideout so we can talk about how much we hate the people of Asgard.
Alessa: Although I should be running away from you, because I have these strange feelings for you; I will go with you. To hide my feelings; I'll be blowing shit up while we head to your place.
Sal: Sorry, what? I was too busy shooting something.
