"Mad Men" season 7, episode 6 spoilers are up and as usual they are ambiguous as ever. It's not clear if Michael Ginsberg, who cut off his nipple in last episode, will be making a comeback and actor Ben Feldman refused to provide any details claiming they are "sworn to secrecy."

In the last episode, Michael Ginsberg flipped out and cut off his nipple before giving it to Peggy as a tribute.

Ben Feldman, who plays Michael Ginsberg, declined to dish out some "Mad Men" season 7, episode 6 spoilers when asked if the copywriter will come back.

"I've been sworn to secrecy like everybody else on that show. If you can get an actor from 'Mad Men' to tell you anything that happen that hasn't already aired, then you deserve an award. It's my job not to say anything," he said.

As it turned out, all the cast of the "Mad Men" undergo a boot camp where they learn how to dodge questions from the media, he said.

The official synopsis from AMC doesn't really provide some "Mad Men" season 7, episode 6 spoilers: "Peggy collects research for a pitch; Pete receives an invitation to an exclusive club; Joan is eager to spend time with her friend," the summary teased ambiguous clues.

And the 30-second video teaser for "Mad Men" season 7, episode 6 doesn't offer much either. It shows Peggy being startled from sleep, then Pete Campbell making a comeback as Peggy welcomes him into her office. Probably to help her with her pitch?

Don isn't too happy either when he confronts Peggy asking, "whose idea was this?"

In another interview, Vincent Kartheiser teased The Hollywood Reporter about the future for Pete Campbell, as well as his rivalry with Ken Cosgrove and Bob Benson.

"I like that there's this guy out there somewhere that Pete judges himself against and measures himself against and wants to destroy," he said in reference to Bob Benson. "That was Ken Cosgrove for the first four seasons."
