Oooh. Interestingly enough Cass is also on track to be a Healer/Mediwizard... although I think aside from perhaps Hamish, no one else is aware that this is the career he actually wants and not y'know go into pro quidditch. Cass is also a prefect, so there's that interaction happening despite him being a sixth year... although he's a Slytherin, so that all depends on that i guess. but he's also Hamish's twin, so there's that too.
then there's allehgra... also a prefect. she has total-bigtime-crush on Cormac, so tends to make frowny faces at the stuff happening in Cormac and Mel's friendship atm (mostly cause she's a silly thing who wont tell the guy she likes him so... yeah).
and have got another character in the works... *runs from Patricia's work stick*
