Do you think Tina has any real right to keep the baby she has produced as a surrogate mother? The baby has none of her genes. I don't see how she can bond with it.
I understood that the Tina/Izzy/Gary baby is 2 months premature, which would mean around 2-3lbs in weight, but the one in the cot looks like a 3 month old?? I think Tina should not keep the baby herself, and the fact that she is keeping it, goes against her the principles she displays on the soap, and so it is totally out of the coro character she portrays.
