ooc: um... Yes, Marcella did eventually tell him.

Snape sat at his desk at the front of the classroom, seemingly engrossed in a thick text. He turned the pages and his eyes, though they scanned the pages, didn't read a single word. Try as he might, he couldn't help thinking like the protective father, and his mind swarmed with ways in which the Lestrange boy could possible hurt Kristi. When Snape finally did manage to get his mind off this subject, he was thinking about Marcella and why on earth he tortured himself with thoughts of her when she was clearly happier int he company of others and miserable with him. The minutes ticked by rather quickly and Snape barely noticed the students who cast glances up at their distracted potions master in between tossing ingredients into their cauldrons.
