It's crazy but Peter, even though he's in critical condition at the hospital, is insisting on having a wedding service performed at the bedside. I think this calls for a no-tarry-marry service. Let's cut out the extraneous parts of the marriage ceremony and get this done before the crash cart arrives. Here's my suggestion:
Minister: Hey BFFs! Check this out. Pete & Lee are doing the M-word.
Minister: Let's assume that Peter has stopped the bigamy thing and Leanne has stopped the escort thing, so we're cool. Right?
Minister: Peter? No playing away and no bigamy, okay?
Minister: Leanne? No more sex for money and no more having it off with Nick, okay?
Peter: I, Peter, am sticking with Leanne even though Cruella, er I mean Carla, is smoking hot in an evil kind of way
Leanne: I, Leanne, am sticking with Peter even though I had it off several times in the Joinery with Nick and once at Gail's house
Minister: By the power invested in me by the Weatherfield & Regional Hospital and the National Health, I now prononouce you husband and wife.
You may kiss the oxygen mask.
