the Episode that Marilla died in?

Well if memory serves me right, there never was an actual episode where Marilla died, because the actress died between seasons they did somehow have some footage of her sick and in bed, as I recall and used it as a memory of Anne's. Her death wasn't mentioned or brought up to much until the Episode where the house was to be sold out from under Rachael and Gilbert appeared in that episode to try and take care of the legal situations. I would say that happend in the last two seasons of the series. I have most of the seasons recorded on VHS. However I am sorry I don't remember which one it is in. I haven't looked at those tapes in years. I hate to say this but I believe there is or was a list of episodes on a site of Kevin Sullivans.

Yes, I watched it a while back on YouTube. It's Road to Avonlea, I think, and it's something like "Old Friends, Old Wounds." If you search for the title on youtube, you should find it.
