I'm good with doing past threads, it'll also establish their current time relationship or at least how they'll react to eachother should their paths cross. Edgar is pretty much a purist when it comes to blood so that alone would put Thomas in his bad books. He'll take any advantage of him he could manage, especially in his NEWT years. We can brainstorm more on this past thread, or if you're more comfortable we can just start a thread and see how it goes. Just let me know if you prefer I start it.

Terence isn't likely to hit on Thomas on his own initiative so romance may not happen between them, at least not in the first year they've worked together. Who knows what the future will hold. We can just focus on them being colleagues and see how that friendship goes. Terence would likely watch some quidditch games during the school year, definitely those of his own House to show his support so certainly could have them sit together during games, unless Thomas is too busy coaching at games.
