Dean pov: so as I'm walking down the corridor to get to potions class, I see Ron and he stops me.
"what do you want?"
And then without responding, just straight up kisses me! So after I kick him where no man should be kicked, I head straight for the boys bathroom, and start crying. Why hasn't Ron gotten another howler from his mum yet? That would be great.
Seamus pov:
So as I'm walking to go to potions, I see Ron, with a clipboard. I quickly run to the boys bathroom and see Dean sitting on the floor crying.
"what happened to you?!"
"r-ron K-k-kissed m-me!"
Okay so he can copy off my tests, rip up my homework, and beat me up, but he can NOT kiss my boyfriend!
"don't worry, I'll handle this."
I run out of the bathroom and find Ron sitting there with his stupid clipboard next to him as he makes out with Lavender. So I take the clipboard, put it into my bag, and walk back to the boys bathroom.
"Dean, look, I got the clipboard he always has with him. It seems to be a list of people in our year, and the ones crossed off are the ones he's kissed.
"come, let's go to potions, I can tell Snape about this."
"t-thanks Seamus."
So at the end of potions I give Snape the clipboard and tell him that Ron has been snogging people for the fun of it, he takes fifty points from Griffindor for that, but gives a hundred fifty to Seamus for telling him. Snape didn't want others to feel how he felt when Lily had married James and how he felt when Lily died. Deep down inside of him, he felt bad for all these students, including Dean, but didn't show it.
