whether the HMs in the regular Summer BB were able to nominate whilst in the secret room, as I can't recall.

I thought that Lee and Casey, although not available to be nominated, would be allowed to nominate as they are technically still HMs, but obviously they didn't, and I can't remember whether Dexter and Gina did or didn't nominate when in the secret room, or whether nominations even happened when they were in there.

Cheers

Gina and Dex didn't nominate, but they did save one of the doomed HMs prior to the lines opening and replace with another. they saved Charlie and put her mum up.

Daley got kicked out before noms so Hazel nominated as usual but was immune

there were no noms the week that Dan went as the house picked the HMS for the secret house and in a twist they were up for eviction.

It would seem that not having had the chance to nominate they will do something tonight I think with the bottom two. The rules seems to be that you still have some say even if you are immune.
