It seems like everyone expects him to get killed. Then they will rally around his dog tag and those of his fallen comrades that he fought for. And I expect Vernage to come out of nowhere to help the team from letting what happened to Mars happen to earth.

Given that it's been confirmed he's getting a new form, I'm thinking he'll turn out okay.

You can't stop Grease, his passion burns too bright.

Since this is the end of this little "Dad" story arc, I would like to talk about I thought was perhaps the biggest issue with the arc and what probably resulted in a lot of people not being that engage with it. I think the core issue comes down to this. After Genius debut, the show has sorta wrapped up a lot of it's long term plots/mysteries. The Dad story arc thus feels like the show trying to hastily come up with a new set of plots/mysteries in order to tie into the end game. It thus felt like it was slightly confused with what direction it was going for. With that said, I thought this episode was fine and nice conclusion to this arc.
