Aw! This was adorable!
George will be lucky if the Spanish don't insist on his imprisonment or even execution on some pretext. They don't like Anne. They will have even less use for any hungry relatives.Hurray, George managed to escape England and their father! Hopefully, he does well for himself here, and manages to find himself a good positon, and if he wishes, a bride suiting his rank.
Why would they insist on imprisoning and executing him? They might be angry about Charles/Anne but imprisoning and or executing her brother would be like +90 steps overboard for treating the brother of their new empress. More likely George would deal with being snubbed/maliciously gossiped about in Charles’ court.
On what grounds?
I personally doubt it. Mind you not all of them dislike her, and it is not them who get to make that decision (And good luck making Charles V do anything he dosen't want to). In fact doing so while she's empress and is pregnant and holds sway over the emperor would be a terrible idea for them to do so. While they may initially be wary of George, I think the nobles will realize that the brother in law to the emperor and uncle to his heir is a very valuable ally to have.
Depends. Council of Trent will happen in more or less 2 decades. If the Catholics are smart, they can "No U" the Protestants using the book. Such as "in the end not even you guys actually follow Luther's words" et cetera, if that makes sense.If Anne were smart she would throw that book of Luthers works straight into the fire...
