With Agents of SHIELD’s season 5 finale being just a few weeks away, as well as Avengers: Infinity War coming out next week, the importance of each episode will only be heightened from here on out. If you don’t think that Agents of SHIELD will find a way to incorporate the most ambitious crossover event in history into its story, then you haven’t been paying attention.
In the last episode, Ruby betrayed her own mother and teamed up with Werner von Strucker. They were then able to corner FitzSimmons and force them to activate the particle infusion chamber that they had just destroyed. Knowing that it will lead to the destruction of the Earth, it only led credence to Fitz’s assertion that time is fixed and they can’t prevent the end of the world.
