- Acting in the Dark: Auditioned for August knowing only what was in the script for "True North". The creators reportedly tried to keep August's true identity a secret from him for ages. The Irony of this was not lost on him.note
- Actor Allusion: Guest starred in an episode of Law & Order playing a war veteran.
- Actor-Shared Background: He was a writer in his youth like the real David Kenyon Webster. Technically subverted with August, as he isn't actually a writer - just pretending to be.
- Billing Displacement: Of a sort. He was listed in the main titles for the second half of Once Upon a Time season 1, although he was absent from three episodes and had only small scenes in a few others.
- Dyeing for Your Art:
- Enforced Method Acting: Because Webster is in the hospital for episodes 6 and 7, Eion took a vacation to India while they were being filmed. This helped drum up feelings of resentment towards Webster from the rest of the cast.
- Funny Character, Boring Actor: He's very soft-spoken and reserved in interviews, compared to the snarky characters he usually plays.
- Playing Against Type: As a Yandere arsonist in Stalker.
- Reclusive Artist: At one point didn't update his Twitter account for five years. And he posts very rarely.
- Short-Lived Big Impact: Two of his more famous roles. He was only a OUAT regular in the second half of Season 1 and only appeared in 5 out of 10 Band of Brothers episodes, yet is one of the more remembered characters in both.
- Typecasting: Tends to be a Deadpan Snarker or Jerk with a Heart of Gold. The two often overlap.
- What Could Have Been:
- Auditioned for Bruce Wayne in Batman Begins, a role which eventually went to Christian Bale. Seen here. Averted in Band of Brothers as he read for Webster and was cast instantly.
- He was cast in a prominent role in Westworld but had to drop out due to scheduling conflicts, and was replaced with Ben Barnes.
