Dr Who: "Image of the Fendahl"

1) Leela rocks. Seriously. I've only seen her in three episodes so far (Face of Evil, The Robots of Death and Image of the Fendahl (spot the connection!)), but I think she's the most fun companion I've yet seen. She's tough, smart, pretty and she treats the Doctor in exactly the same fondly condescending fashion that he treats her. Highly enjoyable.

2) Is there any connection between the Mrs Tyler in this episode and Rose Tyler? Age/time-wise it could be Rose's grandmother or great-grandmother.
