I’m wondering if he might end up being PP? He was in one of the PotC movies, meaning he’s in the Disney/ABC system, so if K&H were secretly searching for an actor in a particular age range and went to the Disney database as their starting point, he’d have been on the list of potential candidates.
If they want to make their PP have a connection to London, maybe even having come from there himself, it’d make sense to hire someone with a British accent. And like I said in my other post, if he’s coming all that way to play a role, it’s gotta be a significant one.
