MO never did his check at 10pm so we can take that as a good indication that Kate raised the alarm before 10pm. Also Fiona Payne as Russell's steak arrived before 10pm. Some wouldn't know the time at all and just agreed with what the others said.

"So me and Matt walked back to the, to the, erm, to the flats, erm, this would have been about, about kind of twenty-five past nine."
"Erm, my food had arrived, well my food had arrived I think by this point. And, and then Kate, erm, erm, returned," (same as Fiona's recollection)
"Gerry, just said ‘Look, let’s just’, erm, ‘let’s just split up and find’, erm, you know, ‘see if we can find her, see if she’s just wandered out’. "

Reply “I’d say it was around ten past nine’ish”.
Tapas timeline says 9.20pm. Rachael also said Jane left at 9.10pm. So why was 9.20pm put on the tapas timeline? That's 10 mins later. If we go by that indication then you move everything before 10pm not after.
