I'm down for stuff with Tavie. If I'm mathing correctly they would be two years off, so not that big of an age gap. A firstie and a third year being friends isn't odd.

However, at the moment Tavie isn't able to go to Ivringly but that is chill if you want to change the location and just leave her out as Tavie is already being threaded as spending her hogsmeade weekend day with her elder sister!
