As much as it pains to me to say, since I still really love her, I think Adjoa probably has to go on Friday.
It's such a shame she's up because she really doesn't deserve to be, but I think compared to Eileen and Sarah, Adjoa probably won't make as good as housemate in the long run.
Added on top of the fact that she kind of thinks she not meant to be in the house, I think it all just leads to an unfortunate fate for her as a housemate, but I think overall Adjoa getting evicted will be a more positive thing for the series as a whole.
