Stranger Things season 5 [now including SPOILERS]

[fourheels]

I don't think Will will have full El powers, more that he can act within the hive mind to affect those connected to the hive mind (the Mind Flayer, Vecna, various democreatures).

I think it's an interesting development, as it gives the good guys a power duo to fight the Mind Flayer/Vecna team. I don't think that any one person will save th world, but that it'll be an "all hands on deck" operation where everyone has to do specific parts toward success (although El will almost certainly have the biggest role with now Will likely having a large role, as well).

I don't know if Will's powers are solely from his connection to Vecna or if he has had them all along but didn't realize it. Regardless, he destroyed the demogorgons just like Vecna killed his victims in season 4 so one way of any, he has access to those powers and it's a nice arc to Will's story to redeem all the crap he has suffer through.

Edited to add that thinking more about some of the lines from the last episode about him being a sorcerer with inate powers as well as his conversation with Robin implies that he has had these powers all along and just didn't realize it.

Also, I suspect the good guys will also have 008 on their team now.
