Trying to take Piper's staff is absolutely a MASSIVE red flag.
Honestly. With her being basically a noble its likely also a serious crime.
Like trying to take the gun from a policeman only worse ?

Him blocking access to the lighthouse is equally so.
Like.. Piper is basically "someone posted a bounty on my head for dead or alive, i want to call my uncle the Iron Judge"

And this guy says no? Like if the situation is a misunderstanding he can explain to the Iron Judge.
Who are remarkable levelheaded. But instead he blocks her access to the light house.

Piper is generally a bad person with entitled attitude.
But she is in the right here.
