We don't know from the editing unfortunately, it would seem the task began once there was only 2 housemates alone by the cherubs, maybe it was designed to be Natalie and Denise, o,r since they do spend a lot of time together it just happened that they were the 2 housemates alone there at the time.
We will likely never know if they were selected for the task beforehand or if it just was them being in that place at that time but in fact it was a rather weak task to be honest so I don't think it will have much impact.

The cutting of Frankie's hair was the best bit of it, that could have been played out more,especially had they got Denise to do it then also got Natalie to get some hair as well. I think Frankie would have got a little more irritated at that.
