So glad when I found this out. Patton Oswalt has been missed on this show for a while now, so it'll be good to revisit the Koenigs, even if it is one of their ancestors (grandfather?). I imagine this'll be the only Oswalt/Koenig appearance in the season, as shows with their final seasons like to bring back a lot of characters for an episode, so this'll likely be that.

Patton OsWalt Special Guest star will come back to Agents of SHIELD in season 7 I cannot wait

I love your theory on being their grandfather, like maybe the first S.H.I.E.L.D. agent in the family. I am just imagining how funny the scene could be- this could also be the way he Koenig family gets involved in S.H.I.E.L.D. in the first place!

BTW I'm still waiting for Ghost Rider

That is exciting. The Koenigs always brought a specific joy to the show and I'm so excited.

Imagine the shock and slight horror the agents would show if they met a Koenig in the past that was identical to the ones they know. LOL

I think they're used to it by now.

I wonder if he’ll have any connection to the Howling Commandos, since Earth-616 Eric Koenig was a member of the team.

Now I just want my bois Ghost Rider, Lance and Bobbi back.
