Losties aren’t the only fans being treated to a reunion by Hawaii Five-0, where Terry O’Quinn will share scenes with Daniel Dae Kim this coming season. No, the Heroes faithful will similarly see Masi Oka meet up with a familiar face, when Greg Grunberg guest-stars on the CBS action-drama, TVLine has learned exclusively.

Grunberg was also the ill-fated pilot of "Lost"s Oceanic flight 815 who was killed (in the pilot!) by the mysterious "smoke monster" (though we didn't know he was a smoke monster at that point, and honestly, by the end, I still wasn't sure what the hell he was, lol).

So there's three "Lost" alumni on H5O now! :)
