So, this is a theory I got to thinking about recently I've heard theories about The Armorer being a spy and some have speculated that The Armorer was this one woman in Death Watch who was among Maul's most devout followers. Here's my theory. The Armorer and Gideon are both former Death Watch and are secretly working together. I think The Armorer joined or helped to form the The Watch to carry on the goal of restoring Mandelor's warrior culture.

However things hit a snag with the older watch members and Din adopting Grogu. I think Gideon and her have decided to cut their losses and start from scratch. So they sent Din and the others to their deaths and left only the Armorer and the loyal mandalorians to watch the children.

I think the Death Watch mandalorians still hold Maul in high regard and now wear helmets modeled after him. Which brings me to what Gideon is working on. I think he's making Zabrack warriors to act as new mandalorians. He's narcisstic but I think his helmet shows he's a major Maul follower and likely sees him as the perfect warrior.

I suspect in his heart Gideon sees himself still as a Mandalorian it's likely he joined the empire as everything else fell apart and became a Moff after Mandalore fell.
