Things with Marvel’s Agents of SHIELD took an interesting turn this week.  It looks like we’re spending roughly two episodes in each time period, and each time period is revealing more of the thread that entwines SHIELD and Hydra.  So even though there are no Infinity Stones involved, Coulson’s team is on its own kind of “Endgame” travel through history to some key moments.  And, unlike the first story of the season, this story saw the team changing the time stream in a significant way: saving Agent Sousa and bringing him onto the team, at least for a while.  Here’s the preview for next week’s episode.  It looks to a lot of fun.
