Who is Grice??
Grice was part of the Eldia revivalists. He was the one to contact Grisha in his clinic and recruited him into their group.
He seemed to be a relatively important member, as he recruited folks personally, but was seemingly still heavily involved in discussions and planning sessions. His relationship with Grisha seemed to be of positive camaraderie, maybe even friendship
However, Zeke’s betrayal hit him hard, and he blamed all their misfortune on Grisha in his final moments.
Ultimately, Sgt.Maj.Gross chose him as bait for the mindless titans, kicking him off the wall to send him running towards the walls, so that he’d lure the titans away from the beach. He’s presumed to be eaten shortly after.
Most of us had thought his story to be finished after chapter 87, but apparently Isayama had other plans up his sleeve: the brothers Falco and Colt appear to be descendants of Grice, as they have his last name.
Though people happen to share names every now and then, there definitely is a resemblance between the brothers and the revivalist.
Isayama has set up some interesting elements and parallels here. The descendants of an Eldia revivalist now serve as Marleyan warriors (like in Grisha’s original plan), and one of them seem to be directly under the authority of Zeke, the man responsible for the old Grice’s death. Furthermore, this is the 2nd sibling-relationship introduced to SnK, and just like the Jaeger bros (my favorite thing to talk about), they are the descendants of a revivalist. In fact, they already serve with one of the Jaegers, and the other one is probably the biggest enemy to the government they serve. I don’t know yet where Isayama is planning on taking the Grice bros, but I’m ecstatic to find out about it.
