Raszagal (spoilers, I guess)

So how eaxactly did Kerrigan get to Raszagal? It doesn't make any sense.

Kerrigan says that she enslaved the matriarch "long before" she joined the Protoss on Shakuras. But Zeratul returns to Shakuras at the beginning of Brood War, and Kerrigan was still on Char at the end of the original StarCraft when the Overmind died. That gives a very short window of oppertunity, certainly hard to describe as long ago in the Brood War timeline.

And that is without even beginning to question how exactly Kerrigan did it. How did she apparantly travel to Shakuras and mentally enslave the matriarch, seemingly without any other dark templar even knowing that she was there?

I use the word sparringly, but this is a big plot hole. It would have been far better and easier if they said that Kerrigan corrupted Raszagal's mind during the course of events in Brood War.
