Hawaii Five-0 is planning their yearly overseas episode, but this time someone will be headed for Afghanistan instead of North Korea.

Executive producer Peter Lenkov nestled his latest Five-0 spoiler into a Valentine's Day poem, tweeting it to his followers before the series' love-themed marathon last Friday.

"Roses are red, Some can be yellow, One of #H50 is headed to Afghanistan, To save a fellow," Lenkov teased.

Unfortunately, Lenkov didn't go so far as to say who will be heading up this mission. Considering Five-0 only has two members with any likelihood of finding themselves in a war zone, viewers are left to speculate on whether or not it will be Steve McGarrett (Alex O'Loughlin) or Catherine Rollins (Michelle Borth).

Although the Navy no longer employs Catherine, an upcoming look into her past has the potential to bring up some form of Afghanistan flashback. Set to be the second-to-last episode of season 4, the plot will involve a "big, dramatic" romantic arc, according to TV Line.

Lenkov told the site that the upcoming episode will include "some flashbacks to [Catherine's] stint in the military. You'll get to know her as a soldier, when she was actually in the Navy."

On the other hand, McGarrett is seen as the military expert of the group. Still employed by the armed forces, the Navy SEAL is always a prime candidate for any combat missions.

Who do you think is heading for Afghanistan? Sound off in the poll below.

Hawaii Five-0 airs Fridays at 9 p.m. ET on CBS and will return with "Pale 'la" on Feb. 28. Click the video below to see a preview from the series' latest episode, "Na hala a ka makua."
