"Dear Uncle Koschei thought that he could kidnap me and get away with it scotfree. Apparently, he'd forgotten what I looked like. Thinking your hostage is human and helpless tends to give them the advantage when it comes to getting the drop on you."
Turning her attention up to her Grandfather, she smirked just a bit, "Tapped into his TARDIS's telepathic circuits and fed my emotions through them. After that left him dazed, I dumped him off on Tersurus. Hopefully he'll have a nice long time to think about what he tried to do."
"Or has had," Susan said, lifting an eyebrow to examine her Grandfather. "You were all curls and Victorian sensibility when he did that."
