Alexander lies to himself that feelings interfere with work, he shoots even better when he thinks about you. Nonsense about romance is so old, if only he knew what he should do. He's not most romantic person around, Viper? For God's sake. Chamber? No way. Phoenix is just bad and Neon is a child. Even Sage isn't good at giving advice like that.
It's not that Russian customs taught him to be romantic either; it's just stereotyping. Flowers are too obvious, candy boring. This world is cursed.
Today was a new mission while others went forward and fought there you both worked in rear protecting backs of allies until the moment when your weapon broke. It is not your fault rather those who created weapon. Alexander saw you on verge of irritation and took his weapon, holding it out for you and taking his spare pistol instead. He was fine with that. He didn't even realize it was an unconscious gift.
— "You can take my weapon."
She said typically cold again distracted by work not that he is cold in principle he is just focused on work and a little awkward when you are around. Give guy some space...
