You shut you whore mouth! LOL!
Tiffany is the most genuine girl on that ship IMO. I also think she's the girl that actually likes the MC the most.
I've always thought something similar. Given her backstory, I'm not surprised that she's acting like she is. But yeah, the connection she feels with him and her true feelings are IMO extremely obvious. She's kind of like the 7-year-old girl who hits the boy she likes.
Seriously, you are so right about this. She's honest, direct, and expects the same. You could go rob a bank with her, knowing she'll have your back even if things go sideways, but cross her, and she'll have your ass before breakfast. The rivalry adds a lot of positivity into their relationship, since she always keeps MC on his toes and forces him to think about what's happening around him. She's a "no bullshit" girl, and I like that about her, especially comparing her to others.
For example: (the names are changed to keep people's anonimity, and avoid drama aboard the Endurance)
Disfigured dairy cow: "I was completely negative about You, when You woke up, but I realized that You're not a bad guy, just a pervert. And now I want You to fuck me like a dirty whore all the time, but the girls look up to me, so we have to wait, I must give them a good example."
Long-legged Mistress of Needles: You know I really like You, but I must keep things professional. I already lost my objectivity, and it's only gonna get worse, if we hook up. But I have no patience, so I wait eagerly for the moment, when You bend me over and fuck the living shit out of me."
Petite religious nut: "How dare You say that my religion is for sex addicts. I'm triggered! But If You want me to stick my tongue into another girl's mouth, so You can prove to me that I'm bi, I'm down for that. (Whispering under her nose: btw, I know i'm bi but I just dont like admitting that in front of others.)"
Miss highest IQ on the ship: "I'm on your side. You have nothing to worry about, since I'm your ally, so tell me everything you know about what's happening. Oh, I forgot to mention: I still keep secrets from You, because I don't trust You. Now let's fuck."
Just to name a few. And Tiffany? She's like: "Okay, tonight I'm coming to your room, and we're gonna fuck like there's no tomorrow. Just make sure to cum inside. What do you mean protection? Of course I'm not on anything, so if You get me pregnant, we'll just have the baby."
I wish every girl was Tiffany level honest.
