Hopes and Time turners

Rose Granger Weasley has disliked Scorpius Malfoy from the second that her father pointed him out on the platform in their first year. But after he went missing at the beginning of fourth year Rose realizes she has.. feelings for him? No no no, this can't be right, he's a Malfoy! But after he asked her out her feelings are undeniable!
on the day she works up the courage to tell him, he looks scared. she asks him why, and he reluctanly shows her.
Could the escape of the daughter of the worst known wizard from Askaban be the missing puzzle peice in their story? or will it be the poison that tears them apart? (This happens during/after the cursed child, BTW)
