I did like that a lot. He knew it was over and accepted it.
But until I see a body................
Warhead in space. But I know what you mean, Season 4's cliffhanger might have a similar endtag: flash back a year ago as a Hive infected meteorite crashlands in some Inuit village as a Inhuman stops his dogsled and picks it up... Son of a b--
Although I suspect Brett Dalton will have some recurring appearances past this point, he showed some depth this season. I was impressed. Or, he may not leave at all, particularly the reveal at the endtag with AIDA and LMDs on deck: additional "Hydra sleeper cell" busting is possible. I doubt they would have Ward back 100% without the Hive/Hydra undertones.
Detractors of Agents of C.H.L.O.E. will probably keep hating on Quake,
but the insinuation that Quake left SHIELD (not necessarily true: double agent?) may have her potentially still stuck as our Audience Advocate (They are right in that the focus of the last two seasons was mostly on her story) or this may take the focus away from her as B-Plot material to bring others into the foreground.
The question is when the time jump occurs: at the beginning, midpoint, or end of Season 3. They could be playing it like the Fallen Agent foreshadow scene that we got when Daisy got the vision of the quinjet moments before exploding. We might see the steps inbetween. Why Coulson stepped down... Why Daisy is being pursued... And possibly if Inhumans decide to thumb their noses at the law to cause SHIELD to rein them in (is Daisy an isolated issue, or is it more X-Men like and Inhumans want their own sovereignty?)
And let's not forget since LMDs were exposed... were the Koenig brothers a beta form of it? Or just identical brothers who all aspired to work in SHIELD at once, which would be really weird?
