What does Karen expect when she makes Sheila choose between her and the baby in "Fiona Interrupted?" Karen is pretty much grown, and has proven repeatedly that she doesn't need her mother. The baby, on the other, definitely does need someone to love and care for it. Considering that he has Down syndrome, he isn't likely to be adopted. Sheila does the responsible thing by taking in her grandson, and the police, when Karen calls them, agree. Sheila makes the only decision she can here.
