holy crap guys, LIE is a week away
John Avery Whittaker is a Time Lord.
The Imagination Station is his TARDIS.
Connie is his companion. Eugene was as well, but he has now moved on with Katrina to have their own adventures.
No one realizes it, but there was a malfunction this one time while Connie was using the Station, and it messed with her time line/circle/wibbly/wobbly thing. This is why she doesn’t age.
