Brooke could get her hooks into Owen, & there could be a great catfight between Jackie & Brooke...

or...

Jackie could chase Eric (at least he's more like her age!), then that would really push OldSteph over the edge! I don't think Steph really loves Eric, they just seem to always hang together somehow.
But being that they are not young & beautiful, & that the actress who plays Steph doesn't dig guys iykwim, then there sure won't be any bedroom/romance scenes with the two of them...
