"My God, it's wish magic."

Connor explains to Vik the notion of “and they were roommates” while both suspect something is going on between Lysa and Charlie. <3

I can totally picture Elaine watching Connor and Vikram with exasperation...

ooh, many! this isn't even close to all of them (and they range from being implied in canon to complete crack), but:

Jenkins wasn't consistently a caretaker. He's had the job since the fall of Camelot but there were centuries where he wandered off to do other things.

Since turning up in the 21st century, Vikram has developed the same music taste as your average 12 year old girl. This is also coincidentally Cassie's music taste.

Flynn has at least one teeny tiny papercut scratch from Excalibur which he bitches about constantly. After the Sword in the Stone it did heal, and then as soon as Cal woke up at the end of s2 he nicked Flynn's arm again. Cue more whining.

Cassie went through a bubblegum goth wild child phase when she was 16-17ish, after dropping out of school and going through the first set of cancer treatments. She lied on some legal documents to get a drivers licence and then felt so guilty that she never used it.

Occationally, when Flynn's bad habit of pacing around talking at 3am is getting on her nerves, Eve isn't above pointed utilisation of the Flutes of Pan.

Connor at one point wrote a paper contesting one of Jake's. He doesn't know this, though, because of Jake's academic pseudonyms - but Jake is sure as hell aware.

The Apple of Discord DID affect Ezekiel. It's not that he was already the worst version of himself, it's that that worst version is identical to the facade he presents and therefore the apple appeared to have no effect.

Lysa hasn't yet realised that regular physics proofs work to confirm that the laws of energy transfer apply to magic. As soon as she does, she's going to be very happy.

Jake's mother was called Rebecca. She died a very long time ago.

Eve got full marks on all her millitary intake exams, and made the jump to NATO more out of boredom than anything else.
