( Cassandra is visibly upset. )

I'm just going to sit here for a few moments. I don't want to talk about it, unless it's to Alex. And you know Alex won't want to talk to me about it, so perhaps you'd best just leave this episode alone.

( a dismissive wave of the hand. )

And please stop squealing when you see other characters from our canon. It's really quite unbecoming.
