EE - Nothing profound, but someone (possibly Dexter or Jay) gave Phil a dancing Santa gift at the garage and he put it on the hood of a car, turned it on, and watched it dance for half a minute, smiling and laughing, then picked up a sledgehammer and smashed it to ****. Funniest thing I'd seen.

Sally on Home and Away discovering Milco was her twin.
Milco was always presumed to be her imaginary friend when the show started but through Milco coming looking for Sally, telling her about their childhood and what happened them and how they were split up, Sally started to piece the jigsaw together. It was a wonderful episode, full of emotion and tied up a story that started twenty years earlier. It also saw Sally come full circle and leave the Bay a few weeks later

Emmerdale have a few stand out ones as well. The storm and siege at the Woolpack. The Christmas where Louise killed Ray - absolutely terrifying and more Halloween than Christmas

The episode following Stingray's death in Neighbours when the Timmins and Sky/Harold/Lou watching a video made by Stingray talking to Kerry.

On second thoughts I have another fave episode – xmas 2012.

Happened to be outside – in October 2012 and at around 1 pm – all these came out in one go – so surreal – later it turned out half of them still wore the clothes they wore at the xmas dinner, anyway, they were:

Alice, Joey, Liam, Tyler & Whitney all walked out together – Jay came out slightly before them, and Lauren & Abi shortly later, followed by – forgot his name, Biancas youngest son. And about an hour later or so, Max’s son - Oscar - that is “both of them” – played by twins - both identical clothes – from Xmas dinner. So not changed for their outing down to Henley Rd.

When I saw the episode for real, it was nearly like being there. And I could see from my photos who had not changed before going out buying lunch.

The ones that stick in my mind are.... The Slater Halloween housefire, Sam digging up Den, Jase's gang smashing up the vic, Stacey's bipolar POV episode, Stacey gets sectioned and many many more I can't think of right now.
