Departure - EastEnders - Jessie Wallace (Kat Slater) When?s she off? Soon. Why?s she leaving? She is having some time off to get over her own tangled love life (sometimes it seems more soap opera than anything on ?Enders) - following her split from Vincent Morse. How?s she leaving? Presumably after a row with Alfie. (Mind you, we could say that of any storyline involving Kat). Should we be sad? Yes, of course. The Square is not The Square without Kat. from Vanessa The Google Girl. my skype name is rainbowstar123
