My 2p worth re: Slapgate...
1. KP, B&J over at CWs house, as evidenced by the photo with the Absolut voka bottle. B&J also have a bedroom there. KP logged into Ps IG, and initiates a conversation with KB.
2. CW gets paranoid, wants the phone, KP throws it to B. CW takes the phone, sees the KB messages, hits KP, gets her on the floor and either treads or stamps on her head and takes the ring. In front of B and most likely J too.
3. KP runs to Hs house, hopefully taking B&J with her, but potentially leaving them with drunk and raging CW which might explain why she seems to have lost further access to them.
4. H has a carer, so I expect that person either drove KP to Kirstys house (with H? and B&J?), or got Kirsty to come and collect her. I think this person is probably the 'Nanny' referred to as having given a police statement.
5. KP is drunk, high, paranoid, hysterical and bruised and possibly having a psychotic episode. Kirsty calls the ambulance for MH reasons. When KP spills the beans about being hit, the ambulance crew call in the police. KP repeats DV story. Kirsty may/may not have added makeup to the bruise and/or given KP a sedative.
6. Over the next 3-4 days, CW persuades KP to come back to him. But how to cover up the DV? Blame Kirsty. Try to frighten KH into preventing B&J from giving a statement, and possibly the 'Nanny' too.
7. Intimidation fails, and B&J have given statements to the police. SS have ensured KP can only see her kids under supervision. KP launches underage rape allegations aganst KH as revenge.
...maybe?
