To be added.
- He has a birthmark shaped like Italy.
- He was betrothed to Daisy when he was fifteen and she was thirteen.
- Sebastian's actor Barrett Carnahan also played Spencer on K.C. Undercover. Sebastian is similar to Spencer in that they're both arrogant bullies who make fun of the "new guy", who is really the main female character disguised as a man. Both end up fighting the disguised female character, and at the end, both characters find themselves schooled by a woman.
- His actor also portrayed Link Evilman from the Nickelodeon series The Thundermans.
