Sci-Fi This Week: Agents of S.H.I.E.L.D., Legends, Grimm, and The 100 Season Finales!

It’s May, and that means a stack of season finales this week! First up is the 2-hour event that wraps up the third season of Agents of S.H.I.E.L.D., as the team’s struggle against Hive reaches its end. It’s been a strong season for the show … but does the end of the season finally mean the end of the road for Grant Ward (Brett Dalton)?

On Thursday Legends of Tomorrow closes out its freshman season as the team tries to put an end to Vandal Savage once and for all, while on The 100 Clarke and the others are confronted with a very different reality in the City of Lights. Grimm also wraps up this week with its own 2-hour event.

Also this week: Katie Cassidy — a.k.a. Laurel Lance — guest stars on The Flash, and the families face their greatest challenge yet as Fear the Walking Dead reaches its mid-season break.
