Pendant the "Brand New Day " episode, it becomes clear that Agents of Shield is playing out the same time travel logic presented in Avengers: Endgame . In short, when things change in the past, it doesn't mean the future will change, but instead an alternate timeline is created. This is why when Captain America and the gang steal the Infinity Stones of the past, their future is not changed.
This is also why Cap returns to return the Infinity Stones at the end: so these deadlines are not changed. Why Cap does appear in the main timeline at the end was a big question we had, but the Russo Brothers explained it by saying that Cap actually uses a Pym Suit forreturn to the OG timeline off the screen. Of course.
Back to Agents of Shield. We see the same logic play out when Mac's parents are killed - Mac doesn't disappear even if he's never born in this timeline. This event led to some confusion among the officers.
"They didn't deserve to die, but that's also the proof you needed, " Daisy's sister, Kora - who died in the original timeline but remains alive here - tells the team.
"Proof that this is a new timeline, " Coulson replies, realizing the inevitable truth. Still, it's when the episode ends that things turn reversible on this timeline.
The alien invaders, the Chronicoms, manage to take down all shield bases, including the Triskelion, seen in Captain America: the soldier de winter. The scale of the destruction is shocking.
The big question now is: can agents save the day on this timeline? And if they manage to save the day, will there be an original timeline to go back to? The team literally has nothing to lose and watching them battle the Chronicles as the series finale nears should be breathtaking. Let's just hope they can find their way home once they save the day. What if you're still wondering where Agents of Shielf fits in the Marvel timeline? We you have covered .
