Daniel Dae Kim has twitted a second picture of him on the set of Hawaii Five-0, along with Summer, co-star Grace Park and other actors. Series writer Peter Lenkov has also confirmed that Summer will guest star on the show.

According to information our friend Nardia (who’s a die hard H50 fan) pieced together, Summer should guest star in episode 16 of the third season, which is titled Kekoa (Hawaiian for Brave One or The Soldier).

The episode, as far as we know, is based on the events that happened in North Korea (as briefly shown in the series’ pilot episode) and is said to be directed by Larry Teng.

If CBS’s programming follows its course, Summer’s episode should air on 18th February 2013.

Update: New picture of Summer and Joel de la Fuente.
