Dominic Monaghan — “Lord of the Rings” hobbit and the man once known as redeemed drug addict Charlie Pace on “Lost” — recently made a striking statement on Twitter. It was the sort of thing that simply does not fit succinctly on one’s hand the way that “Not Penny’s boat” once did. During a Q&A with fans, one woman asked him if he would convince his former co-star Matthew Fox to join Twitter. Monaghan’s response was a jaw-dropper:

@omggbeccaa he beats women. No thanks.

Yes, Charlie Pace flat-out called Jack Shephard an assaulter of women. And just in case anyone thought he was kidding, or that his fingers were momentarily possessed and tweeted the wrong thing (maybe he meant to say “He beatboxes about women?”), he then said this:

@omggbeccaa how do you know we ever did?you don’t know either of us.he beats women.not isolated incidents.often.not interested.

And then he added this:

an accusation is when you ‘claim’ someone did something wrong. i know.”

When a Twitter follower suggested that Fox could sue him for making such public statements, he responded:

@Fate815 @omggbeccaa and it’s very difficult to sue someone for speaking the truth. Have you received an education dear?

In the words (word, really) of Hugo Reyes: Dude.

These comments sat largely unnoticed on Monaghan’s Twitter feed late Sunday and all day Monday, until Tuesday, when Jezebel picked them up. Then RumorFix followed suit, followed by Vulture, followed by multiple other media outlets.

Look, let’s be clear about one thing first: We don’t know that Fox has hit several women and does so on a regular basis. We do know that he was accused of punching that party bus driver last summer in Ohio in a case that still may go before a civil jury. But that’s all we have, from a public evidence standpoint, to go on; he and his reps have never commented on that situation, nor his DUI charge from earlier this month, nor Monaghan’s recent comments.

Update: TMZ now reports that sources “directly connected to Matthew Fox” say that the actor “has never beaten any woman in his life” and that it is “baffling to Fox as to why Dominic would go on such a rant.”

All that being said, if Monaghan is right — and he seems quite confident that he is — then the saddest thing about this whole affair would be that women were victimized and remained silent about it. Open. Shut. The end.

But it’s also striking to see an actor call out one of his colleagues for committing alleged criminal behavior, and to do so in such a blunt, damning manner. Some think Monaghan is brave for speaking up; others think he’s a jerk for ratting out a former co-worker and friend. Either way, it’s an astonishing thing to witness, even in this era of excessive mouth-running on Twitter, Reddit and Facebook. Celebrities occasionally dish about each other, but they usually keep their mouths shut about the purported darker sides of their fellow colleagues’ natures. And for “Lost” fans, this whole thing is a bit depressing because it blows to smithereens that admittedly naive perception that everyone on the show was surely great friends with each other. I mean, they survived a plane crash together. And then they all reunited at the end in that church and hugged and agreed to walk into that weird white light together, which was heart-warming even though it totally ticked off millions of people. And Charlie Pace’s life was saved by Jack during the flash-sideways, so they must be really tight in real life, right?

Well, no, said Monaghan in that tweet embedded above. “How do you know we ever did?” he asked the fan who wondered how Monaghan could say such things about Fox when they shared so many good times. “You don’t know either of us.”

He’s right. We don’t know them. But because we watched them on a TV show that we deeply loved, we feel like we do. And for some reason, that love makes many people want to believe that the sense of community that was such a consistent theme on “Lost” translates into the real world. But it didn’t necessarily. At least not for everybody.

Although, if it’s any consolation, Monaghan and Jorge Garcia still seem to be on the kind of good terms one would expect from the Charlie/Hurley friendship. After Monaghan referred to Garcia as “extremely huggable,” during that Twitter Q&A, Garcia tweeted him back.

@DomsWildThings @schoonoverandy yeah but Dom’s the big mouth kisser.

— Jorge Garcia (@jorgegarcia) May 29, 2012

Garcia has not tweeted at all about Monaghan’s Fox comments. But since we’ve established that we tend to think of these individuals as their characters even though they clearly are not, I can only assume his response to this whole episode mirrored mine: Dude.
