However, in the show, it wasn’t public knowledge until recently.
But there are many other villains who could fit the bill.
But that’s too obvious.

Is “General Hospital” really going to go back to that well?
No, Alex is a more likely candidate.
But presumed death hasn’t stopped other characters from coming back before.

He got 30 years in jail in 2016 and still remains there.
Paul could very well have been stewing in Pentonville, plotting his revenge against Anna.
He may even have set Paul up with the untraceable rifle.

Paul could use her current turmoil as a smoke-screen to hide his agenda to terrorize and ultimately kill her.
Probably not a smart move, even for a cunning killer such as herself.
She has mob connections, and burning someone’s house down to terrify them is right in her wheelhouse.

Thus, the two formed an unlikely friendship that’s lasted to this day.
She’s starting to suspect that maybe this mysterious group was behind the attacks on her.
It’s very possible that Pikeman is not only trying to kill Anna but Sonny as well.

The agent ended up being the good guy and changed his name to Grant Andrews.
He captured Anna and terrorized her with his German shepherd named Satan.
Soap Spoilertook things even further by theorizing that he’s the one behind Pikeman.

Painting words on her door and lighting her house on fire is easy-peasy.
