It’s not that surprising, really.
If you take someone like Molly and try and mould them into something they’re not, at some point, they’re going to break. Even if they’re a straight-A student and they’ve read every book they should’ve, and they’re not rebellious and they’re beautiful and well-dressed and polite and friendly, they’re going to snap one day.
Obviously, it would be Lorcan.
Subconsciously, she’s always kind of been jealous of Lucy. Lucy is such a dreamer and she’s so gorgeous in a different way to Molly; and all the pressure is on her sister, so she can be happy and free. And she’s got Lorcan, and everyone knows he’s so much nicer than Lysander.
It happened kind of suddenly, after too much apple cider and a revelation that shook her whole world. Obviously, everyone expected Molly to fall for Lysander and Lucy for Lorcan – so she fell for him because she doesn’t like disappointing people.
Lorcan loves Lucy, he truly does, but by the fireside Molly’s hair (that hasn’t been brushed in three weeks) looks so much more alive and perfect and of course it’s her, it always always was. Somehow, it’s so much more beautiful to watch someone perfect fly from the cocoon their parents have trapped them in, than to watch Lucy, who’s always been a free spirit.
(Maybe, Molly Weasley needs a change from perfect.)
She puts pink and purple and green and blue streaks in her rats’ nest of hair; gets a tragus and a helix piercing in one ear, and an industrial in the other; and gets a pair of angel wings tattooed on her back – ironic, since she’s far from it, nowadays.
She steals Lorcan Scamander.
