Winged Pig wrote: Also, a few more Hot Seat questions:

Will we see Hyperion Heights again?

Probably not, but there is always hope. Even if Mary Margaret isn't appearing.

Will we see Gideon again?

Yes. He plays a fairly significant role in the season

Will we ever find out who is the only unknown Coven witch (from the ones who cast the curse)?

There are no immediate plans for this arc. Maybe in Season 8B.
