Dominic Monaghan is appearing in ABC's new promo campaign, but according to EW, it has nothing whatsoever to do with Charlie Pace being resurrected on Lost.

But that's what the network wants folks to think.

Why? Because they're trying to keep under wraps the real reason he was playing table soccer with Patrick Dempsey, Courteney Cox, and Ed O'Neill in that clip.

Monaghan is featured in that spot because rather than coming back to Lost, where he starred for three seasons, he's actually joining the cast of another hour-long ABC drama series as a full-time regular. And ABC wants it to be a surprise.

A big surprise.

Our question: Why on earth wouldn't ABC want people to know which of its shows' casts would be augmented by Dominic Monaghan, a popular actor from Lost, and also the Lord of the Rings trilogy and the summer blockbuster X-Men Origins: Wolverine?

• Could it be because the show Monaghan is joining is none other than Grey's Anatomy, and making the announcement could spoil the show's summer cliffhanger?
• Could Monaghan be taking over the role of George O'Malley from T.R. Knight, or playing a new character altogether that ABC nonetheless wants to keep secret?

We have no evidence to suggest this is actually happening other than what you just read above. It's just a rumor, and we are just throwing that out there. Thoughts?
