... was that appearance in the live episode a one off?

that was a tease of sorts she is to make a full permenant return later on this year also we are due another tease in due course

Thanks. 😊

We'll get another Kathy 'tease' soon. When she eventually returns full time in 2020, she'll be revealed as Shirley's secret sister.

Cannot wait to see Kathy v sharon

Another tease from Kathy coming very soon and a full return later in the year.

Same

Ian's reaction will be epic

She's coming back soon, thankfully. Should never have been 'killed off' in the first place. Thank god the 'death' plot was so wafer-thin (a few references in the script at most), enabling her to return.

Me too! We haven't had a good cat fight on EastEnders for ages .

It would've been funny and, as the young people say, random if it were just a one-off appearance and never referred to again!
