SPOILER WARNING: This article contains major spoilers for "Best Laid Plans," the latest episode of Agents of S.H.I.E.L.D.
Agents of S.H.I.E.L.D. just brought the dead back to life -- again. In "Best Laid Plans," the latest episode, Tess was resurrected following her death in "Fun and Games."
Tess returned to the human levels of the Lighthouse as a messenger sent from Kasius. When whispers of a messenger made their way to Mack, Yo-Yo and Flint, they went to see what the commotion was about. The crowd parted to reveal Tess, who appeared pale with massive black bags under her eyes.
Tess' haggard look didn't deter Flint, who was overjoyed at the sight of her. "Tess! I thought you were dead!" he cried as he ran to hug her, to which she replied, "I was."
When they had a bit more privacy, Tess began to explain how she was killed and what brought her back to life. "I fought, then I begged. They dragged me to the Exchange. Knives are cold," she whispered. Mack expressed his sympathies and told her he was glad she was back, only for her to say, "But I don't feel the same."
"I was dead, and then screaming, my heart on fire. Kasius was there, smiling," she continued.
That's when something clicked for the two time-displaced S.H.I.E.L.D. agents. "S.H.I.E.L.D. dealt with something like this before," Yo-Yo explained.
"In our time, we've seen Kree biology bring people back," Mack agreed. He is likely referring to Coulson's miraculous return from the dead. In Season 1, Coulson slowly discovered that he had not been sent to Tahiti to recover from his Avengers injury; instead, Nick Fury had subjected to him to an experimental -- and potentially dangerous -- surgery, which used Kree biology to resurrect him. The experiment had some side effects, including memories that weren't his. These memories led to the discovery of Terrigen and, subsequently, Inhumans. He has been side effect free ever since.
"Kasius said that he'd smothered the fires of death with the blood of the eternal. That's how he talks. It's horrible," Tess recalled. "Kasius is a god. That's why I'm standing here, as proof." She then delivered her message: Kasius wanted Flint, everything he needs to keep breeding Inhumans, every child older than 10 and motivation for Quake, the Destroyer of World, to return.
As the first pod of Agents of S.H.I.E.L.D. Season 5 hurtles towards its conclusion, it's unclear how Kasius' ability to resurrect the dead will factor into the season. However, that -- and the fact that Kasius has his own seer -- certainly spells trouble for Coulson and his team.
