It is basically to display her arrogance.

Well, you'd shown it very well, especially since she never killed the present Mother Russia's grandma.

Very true, which was an obvious lie.

Nod to that.

I wanted to show how devious and evil she can get, by trying to bait Katherina, because she knew that the her and the current Mother Russia don't see eye to eye half the time.

It was to play off the prejudice.But Katherina and Olga did remember what Col. Lewis said before he died in Afghanistan. "Don't let Adolf and Josef rule over you."

You've shown that pretty well.

Oh, she'd remembered that alright. There's a difference between not seeing eye to eye on things, and wanting to kill each other over disagreements.

Yep, just like in real life. These are among the many things, that Katherina and her family MUST BEWARE of.

I'm sure that the rest of the family is aware of this, especially the older members.

True enough, but reminders are there. But I'm very sure, she remembers and has a LONG MEMORY.

Agree on both count.
