We’re back with another Side Quest Review for Season 4 of Invincible, this time diving into Episode 6. Picking up right where things left us, the aftermath hits hard and doesn’t let up. This episode leans into the growing bond between Nolan and Oliver, giving us some surprisingly heartfelt moments while Mark is sidelined, recovering from a brutal, near-fatal attack. At this point, you have to wonder… is Oliver sending Nolan a Father’s Day card after all this? Meanwhile, the war is officially underway. Our heroes come out swinging, but as we know, it’s not about how you start—it’s how you finish. The cost of this conflict is already steep, with major losses that leave a lasting impact… even if Thaedus brushes it off as a “small price to pay.” We break it all down in this review. And if you missed our earlier discussions, be sure to check out our Side Quest Reviews covering Episodes 1–5.
