Adric: Nyssa is dead!? Tegan: Yeah, we got along a lot. I'll miss her. Adric: Me too. She was always trying to kill me. Tegan: I know. Me too sometimes. In bed. Adric: In bed? How's that? Tegan: Never mind. Adric: We can do more than just grieve... Doctor: NO! NO WAY! WE'RE NOT GOING BACK NO MATTER WHAT. dON'T EVER ASK ME AGAIN TO DO THAT BOTH OF YOU LISTEN! THERE ARE SOME RULES THAT CAN'T BE BROKEN EVEN FOR THE TARDIS... Adric: Doctor, I was just going to ask that we go back and watch her die again and again and again...and again.. Doctor: I've already plotted that to cheer us all up. Tegan: Doctor, are there any planes involved? TDF: no redeeming value at all.
