Love potion

It wasn't a love potion. Lavender had a crush on Ron, and when they went out, he was just so excited to have someone actually like him like that, so he just went with it. But Ron got sick of her in like the first week.

Didn't she try to date-rape Harry (love potion) but Ron ended up taking it instead?

That was Romilda Vane

Oh right it wasnt the love potion just remembering the first part of the movie where they mention the love potion thx
