I can't believe she's become that desperate. Yeah, he might not mind having another child like Jack/Joel, but that would because he's messed up with his own daughter. To be honest I don't see Owen in a long term relationship and if Ronnie was to get pregnant by him, both would want the child to themselves if they did split up. Then there's the issue of him trying to kill his own daughter. He could try it again if they had a daughter and Ronnie would suffer some more, and then there's the fact that her daughter was murdered. It's bad enough that Danielle's dead anyway but considering the circumstances I would've thought the whole murder thing would put her off even more.
