My hopes are that there will soon be more of Maddie, of course, but also of jazz and Valerie too. I hope that at some point Danny will decide what kind of relationship he wants with each and every woman. For example a love relationship or a purely sexual relationship. It would also be great if there were critical moments where, for example, the marriage of Maddie and Jack is at stake. Whether their marriage ends and Maddie chooses Danny as her new husband. Or whether the two just continue to have a secret affair.
And of course I hope that Danny can eventually impregnate all women (people and ghosts).
