Season 3 of ABC's superhero series "Agents of SHIELD" concluded on a sad note as two of the prominent characters from the series, Hive/Ward (Brett Dalton) and Lincoln (Luke Mitchell) ended up dead.

However, the major surprise in Season 3 finale was a sneak peek into what might come in Season 4 of the series.

In the last episode of Season 3 titled "Ascension," viewers got to see six months into the future. A rogue Daisy (Chloe Bennet) was seen, with Coulson (Clark Gregg) and Mack (Henry Simmons) in pursuit of her.

Another surprise came when Coulson revealed he was no more the director of Strategic Hazard Intervention Espionage Logistics Directorate (SHIELD). Elsewhere, Dr Radcliffe (John Hannah) also revealed he was all set to launch a program known as "LMD Phase 1," while the shadow of a female humanoid was seen behind a glass door.

According to Ecumenical News, Life-Model Decoy (LMD) is a duplicate of an existing human being, very similar to the Koenig (Patton Oswalt) brothers. From the looks of the Season 3 finale, it seems Dr Radcliffe's version of LMD will cause more trouble than good.

Talking about Radcliffe's importance in Season 4 and how his LMD inventions will affect the story with IGN, executive producer of "SHIELD," Jed Whedon, said: "We can say very little, but we can say Radcliffe, he has a good heart, but he's dead set on scientific advancement. He thinks he's solving a problem right now, and he says: 'Fitz and Simmons had friends die, maybe they didn't have to.' I think he thinks there might be a solution to some of these problems they've faced. Whether or not he's creating a solution or a new problem, we'll have to wait [and] see."

"Agents of SHIELD" season 4 will air in fall with a new time-slot on ABC.
