Now that NBC has not-so-subtly let it slip that the guy Carol Hathaway married is returning to ER tonight (Yes, that guy!) we at theTVaddict.com thought we would take this opportunity to ask the following obvious, albeit slightly awkward question.
Will he-who-shall-not-be-named actually play a substantial role in tonight’s episode? Or will NBC take a page from last month’s GREY’S ANATOMY/PRIVATE PRACTICE playbook by only offering up a half-baked scene to ensure we all tune back in next week, and thus, milk these final four episodes for every ad dollar/viewer they can?
Knowing NBC as we do, we’re going to bet on the latter. How about you? 
Thanks to KorbiTV for the Tip!
