According to the TV Line one of How I Met Your Mother‘s most enduring mysteries is about to be solved TV :
Dexter Emmy winner is nearing a deal to play Neil Patrick Harris’ onscreen dad, Jerome Whitaker, in one episode later this season.
Questions surrounding Barney’s MIA papa have dogged the legendary lothario during much of the show’s run. Red herrings he encountered on his quest included everyone from Bob Barker to Ben Vereen (a.k.a. his half-brother’s dad, Sam).
It’s not clear how or exactly when Barney will come face-to-face with his estranged dad, but it’s safe to say said reunion will be… wait for it…
The episode, titled "Oh Honey", will see her play Zoey's (Jennifer Morrison) cousin, described as "a beautiful, naive girl who the gang resorts to calling 'honey'."
