Any time Grey's Anatomy spoilers are referenced, you have to take them with a grain of salt. The term is practically a misnomer, given how shrouded in secrecy the program is.
But a TV Guide insider is revealing a possible (but we would have to say unlikely) rumor that we nonetheless thought would be of interest. The magazine's Michael Ausiello writes:
Speaking of which, did you all catch the special Grey's Anatomy-centric Oprah two weeks ago? And if so, how uncomfortable was O's little powwow with Washington, Patrick Dempsey and T.R. Knight? I haven't witnessed such a forced reconciliation since the late '90s when Cybill Shepherd and Christine Baranski went on Entertainment Tonight to proclaim that everything was hunky-dory on the Cybill set."
We personally don't believe Dr. Burke is going anywhere, especially since he has received the full backing of Shonda Rhimes publicly and his character is as central to the show as ever before.
As far as Ausiello's take on the Oprah visit, it's hard to say whether they were uncomfortable or not, as interviews are not scripted and don't often catch people at their best. We thought they looked fine.
