The latest casting rumor for season 5 of Agents of S.H.I.E.L.D. could mean a crossover with Inhumans is on the way. There's no telling how much longer Agents of SHIELD will be on the air, but it's certainly not holding back in the meantime. After introducing LMDs, Ghost Rider, and a world ruled by Hydra last season, the show is all set to continue exploring its past as it heads into a new future. A big part of that will see the series dive further into the cosmic side of the MCU.

After Agents of SHIELD introduced the concept of Kree and the Inhumans to the MCU, the show will be heading back to explore those elements this season. Both the Kree and a version of their mysterious Monolith will be coming back on the show this year, and its seems that aliens in general will be a big player in the new season. Meanwhile, the addition of Natalia Cordova-Buckley (Yo-Yo) as a series regular means the non-Royal Inhumans of the series should get more of a spotlight.

Furthering the news we've been receiving over the past few weeks, That Hashtag Show is reporting a new casting rumor for Agents of SHIELD season 5. According to their sources, the show is seeking a stunt performer to portray the Kree assassin Sals-Bek for a two-episode arc.

If you've never heard of Sals-Bek, don't worry. He's only ever appeared in one Marvel book, 1995's Inhumans: The Great Refuge. His small role in that issue, however, could hint at what to expect when he arrives.

We've seen various Kree come to Earth on Agents of SHIELD before, and each time they've been hunting someone. Likewise, Sals-Bek role as an assassin likely means an Inhuman is in trouble. In the comics, however, he's out to kill the Royal Family while they're stuck on Earth. With Medusa, Black Bolt, and other members of the Royal Family in that very predicament now on Inhumans, could Sals-Bek's arrival means Agents of SHIELD is gearing up for a crossover?

We've already heard the rise of NuHumans from Agents of SHIELD referenced on Inhumans, and both shows are on ABC. Given that, it wouldn't be surprising to see the two share a deeper connection at some point. Even if the Royal Family doesn't show up on Agents of SHIELD, perhaps Sals-Bek's mission to find them will see him confront Coulson, Quake, and the rest of the team. We'll have to wait a bit longer to learn more, but things should become clearer as the premiere of Agents of SHIELD approaches.
