Well Emma said something on bbbots like Detective Dan was back so maybe there is some base to that,unless he is just coming on bbbots again.
Evicted housemates have visited the house again in the past, Ben Duncan went back in and was famously handcuffed to the awful Mario for the time he was in for a visit.

I would guess even BB should need to do something as to any,even tiny,conscience they may have after him being robbed of his place in the house.
