Have you noticed the difference within the group on mandalorian soldiers working for maul

So among the mercenaries of maul there were 3 mandos which turned traitors and were disrespectful/betrayed rook kast while the others followed her and respectfully referred to her as ,,Lady Kast”

1.Does this mean that rook kast is a mandalorian noble similar to how bo katan is referred to as ,,Lady” given her house of Kryze origin?

2.Do you think the loyal mandos are part of the house of kast and therefore serve her so loyaly because she is the noble that governs over them similar to how ursa wren also had her clan army?

3.Does this mean that the entire house kast serves maul given that probably their strongest warrior-rook is with him?
