Thanks to Judy for collating all this for us.
#Lost filming happening right now at Rehab! Lady in blue sweater standing in front of information desk; not sure if she's part of a scene.
For the #Lost scene, 1st floor of Rehab has been turned into "Sun Palms Nursing Home".
Jack's in this #Lost scene!
One of the #Lost extras is named Alex; he's wearing a plaid shirt. 'Cause you know... that's important stuff...
After filming, I asked the "receptionist" what the scene's about. "Jack's visiting someone at the hospital". I love detailed descriptions...
For 5 years, I had to listen to people talk about their #Lost actor sightings. Today, I got to sit in on a filming. I can now die happy. =)
