Alina was still thinking of how her plan of running away with Marissa will work out, from the look of things it's obvious that Marissa has something for Giovanni, so she wouldn't agree to leave, she would bring up the baby as an excuse not to leave New York.
She has never really been a fan of changes, since the first change she experienced was losing her father to the cold hands of death, and she knew how tight the bond between her and her old man was.
So, she's probably feeling safe with Giovanni, Giovanni has deceived her with the flashy lifestyle of his and luxuries which she never had, but if it comes to that, Alina knew that Marissa wasn't someone who could be easily swayed with money, so it's something else.
