First, she claims Tani's power. That was the purpose, so it's very fine.
Then, she claims this corruption for herself. That's an impressive feat, so it's very fine.
Then, she claims a complete Crown of the Shakyn making her the hidden ruler of her universe. That's a whole lot and things start to get crazy.
Then, she goes into Tani's palace, claims it, outgrows it, then reshapes it for her own tastes. OK, that's starting to get evil and worth of a true Shakyn.
THEN! She claims Tani's very own outfit for herself and takes delight in showing it off and rubbing it in Tani's face!
Now, that's just simply and without any doubt... something beautifully Shakin-y to do. Seriously, if she was hir daughter, Tani would be so proud.
Something tells me she might go into "grabby hands" mode when she'll find Tani's weapons (which will soon be revealed).
