Fans of "Lost" were left with a lot of lingering questions after the show's series finale --  but this probably wasn't one of them.

Dominic Monaghan, who played heroin-addicted rocker Charlie on the show, appeared on Bravo's "Watch What Happens Live" on Tuesday, where he was asked to reveal which of his costars "smelled the worst" on set.

And Dom didn't Plead the Fifth -- he actually gave an answer. See who stunk in the video above.

The actor was also asked why Michael (Harold Perrineau) and Walt (Malcolm David Kelley) didn't appear in the church at the end of the final episode ... what he thought about hated characters Nikki and Paulo ... and what he stole from the set. 

Monaghan had an answer for everything. 

While we wish Andy Cohen had asked about his real life ex and costar Evangeline Lilly or his feud with Matthew Fox, we'll take whatever "Lost" answers we can get.

The cast recently reunited in Los Angeles, sans Dominic, earlier this month. 

Ian Somerhalder, Josh Holloway, Malcolm David Kelley, Maggie Grace, Yunjin Kim, Jorge Garcia and Henry Ian Cusick all met up for a Q&A for PaleyFest with executive producers Carlton Cuse and Damon Lindelof.

When asked about the controversial series finale, which didn't answer quite as many questions as fans of the show had hoped, Cuse was ready to defend himself.

"We felt like Lost was sort of the Big Bang Theory [not the TV series] and every question would only beget another question," he said. "But what we cared about most was the emotional journey of each character."

"Obviously, there are all these mysteries, and in the final episode of 'Lost,' we could answer a question that wasn’t asked," Lindelof added. "What is the meaning life? And what happens when you die?"
