The upcoming episode of "Hawaii Five-O" Season 7 would be more interesting as it was reported that there could be a possible crossover of "MacGyver" in hit CBS TV series. On the other hand, there were speculations that Catherine Rollins and McGarrett's relationship might have a second chance.

Though there were certain reports and theories that most of the main characters of the hit TV series would be leaving the show, "Hawaii Five-O" Season 7 would still be interesting to watch as the American action-adventure television series, "MacGyver" could possibly have a crossover on its upcoming episode. In fact, the two TV series were both reboots and they have common executive producers.

The executive producer of "Hawaii Five-O" Season 7, Peter M. Lenkov revealed that he had plans for a crossover. He admitted that it wasn't that easy to reimagine a hit and shared his thoughts on how he could get it right. In his interview with TV Insider, he alluded that an aviator and old friend of MacGyver, Jack Dalton knew McGarrett in the military.

"I took a shot out of the MacGyver pilot in a flashback to Jack [George Eads] in Afghanistan. The shot was off the saddle of his gun. It said "Aloha" on the saddle, and the idea was that he knew McGarrett [Alex O'Loughlin] in the military. I still would like to take advantage of that. Somehow we'll do a cross-over and those two guys knew each other. I'm hoping"

On the other hand, there were speculations that the romance between Catherine Rollins and McGarrett could have a second chance. The love team between the two Hollywood stars in "Hawaii Five-O" brought hits in the said TV series. The fans and viewers of the show kept on hoping that the former couple would still end up together. However, there were no confirmations yet on which episode would Catherine expected to appear. Possibly, Alex O'Loughlin would be back on set.
