"Oh bugger, don't tell me you had this all planned out!" He laughed, trying hard to look serious when he barely could keep himself from laughing really hard. "I'm sure you're very good at Divination, I never was any good in it, and you knew I'd be here this very second...you tricked me. I'm deeply hurt." He buried his face in his hand for a moment.
"Oh, Transfiguration...I was forced, really. McGonagall forced me to be good." Oliver explained, sounding really serious. Actually he was serious. "I was in Gryffindor after all and she threatened to ban me from Quidditch unless I got an Exceeds Expectations in her class." he paused briefly to think. "And I think I actually had some talent for it. It's not been all that hard for me...maybe if you want and if I'm not stuck with the workshop all day I could try to help you out?" he offered. The evenings were usually rather boring, because he didn't fancy to spend them with the teachers and most of the students he knew from his house were too busy doing homework.
