I just spoke to someone who had interactions with both George Takai and Lisa G and he confirmed that Robin had ovarian cancer that has spread to her colon. I would assume that she is undergoing chemo and or radiation, as well as having a good chunk of her colon removed. This would explain the long absence from the show, hair loss and embarrassment from a colostomy bag. She can go out but it will be immediately obvious to anyone that things just aren't the same with her appearance. Now I find her as annoying as the next guy, but I honestly wouldn't wish this on anyone. The problem I have is the obvious vanity and shame that she is exhibiting, countless celebs have been upfront and real about their cancer, if anything, it helps others by identifying with them. The other thing I heard is that she had known about the cancer for 5 years previous and was trying everything she could to beat it, non conventionally of course (ayawasca) This fact would elicit a humongous "I TOLD YOU SO" from anyone, especially Howard, but because it is too late, no one is beating her with that stick. Now go ahead and mention the pickle jar.
