Hi, yeah, one of the best games out there.
Playing from the beginning as a reminder of everything, and noticed some unmatched idk, conversation? Anyway, spoiler (or not) 
In 1st pic he is asking her if she is Nova
She clearly tells him that she is not , and who she is , but after 
She is asking him if he is one of her friends, i mean.. He just literally asked if SHE IS NOVA, he CAN'T possibly be Nova's friend now, can he? And after that 
The just pretend that they have already met. It doesn't match , whole conversation felt illogical. Well, just wanted you to know if you weren't aware.
Anyway, game is great, good luck!
