I love the appearances Zee made in Dini's Detective run (and his ret-conning the DCAU childhood friendship of Bruce and Zatanna into DCU continuity). And even though I never saw it before during her appearances in 'Tec I could totally get onto the Bruce/Zee romance boat. They do have history, chemistry and she can lighten him up and since she's out of town a lot it could work as a long-distance thing. Ironically it's because of DIni's push for the ship that I totally never bought it that Zee would suddenly be gung-ho about promoting Selina to go after Bruce in Dini's Heart of Hush storyline. Just a few issues earlier she had wanted him for herself.
It will be interesting to see what Dini does with Zatanna and Batman if he's still on the Batman book when Bruce comes back (the Zatanna on-going he's writing should be out by then as well).
