This episode just wouldn’t quit. It shouldn’t work as well as it does: piling character after character into what was, at least on the battlefield, a one-on-one duel between Saber and Caster, but because of the build-up in the previous episodes, each and every time someone new takes the stage, it adds a new glorious layer to the conflict.
And even if this battle only turns out to be a big tease, now six of the seven Servants have met one another, and have at least a cursory idea of what to expect form each other. We also learn that if there’s one Servant who’s going to keep a kind of noble order and balance in this War, it’s Rider.
When Lancer declines out of obligation to his Master and Saber is insulted by Rider’s offer to make them his retainers, the Master who originally meant to command Rider appears, at least in voice-form; Archibald is tickled that Velvet would actually become a combatant in the Holy Grail War, and intends to teach him a lesson.
\Rider isn’t having that. Whoever this Archie guy is, he won’t let him torment his Master (that’s his job), who is at least by his side. He calls out Archibald for hiding like a coward, and calls out any other Servants who were drawn to Saber and Lancer’s excellent duel (though if he found it so excellent, why not let it unfold rather than interrupt?)
And so two more Servants appear in quick succession: first Gilgamesh / Archer, then Berserker (true identity unknown). Gil, as is his wont, deems all other kings in his presence to be pretenders (and he has a point, he is the first of them, historically speaking). But Matou decides that now is the time to test Berserker—as well as his own tolerance as a Master.
Archer takes Matou’s bait and exposes his Noble Phantasm for all the other Servants and Masters to see, but ends up with nothing to show for it, since Berserker is not only crazy, but an extremely tough customer, turning every blade Gil sends his way into his own NP. Ultimately Tokiomi has to spend a Command Seal to reign Gil in.
I love how powerful, frightening, and unpredictable Berserker is depicted; he’s a very cool design that seems to shudder in and out of solidity, as if he’s just barely being kept together.
But what I loved even more was Gil’s attempt to save face by basically saying “You’re all beneath me; kill each other off until there’s one left and then come at me.” He’s an arrogant prick as always, but he’s surprisingly likable in this version—perhaps because he was thrown off his game so effortlessly by Berserker.
With Archer gone, Berserker turns his attention (such as it is) to Saber, whose injured hand quickly puts her at a disadvantage, forcing Lancer to save her from a potentially vicious blow. He doesn’t do it because they’re friends, or allies, but because she’s his opponent. If Berserker wants to fight her, he’ll have to get past Lancer first.
That’s Lancer’s will, but unfortunately for him, Archie has Command Seals, and uses one to override that will, ordering him to team up with Berserker to eliminate Saber. In the ensuing one-on-one (after Lancer apologizes to Saber), Kiritsugu and Maiya have their weapons trained on Archie and Assassin, respectively.
Their careful work is ruined, however, by Rider (again), jumping between Saber and Lancer and driving Berserker into the ground, forcing him to retreat, then telling Archie to order Lancer’s retreat as well. Rider has decided that no one is going to die tonight, and nobody challenges him.
I have no doubt that Saber would have gladly fought Berserker and Lancer at once, bad hand and all. But she’s clearly grateful to Rider for his intervention this time. The primary reason for that is Irisviel: if Saber falls here, she’ll be on her own, surrounded by enemies. Rider also decides to stay out of Saber and Lancer’s fight from now own; he’ll face whoever prevails.
That’s fine with Saber; she can’t fight anyone else at 100% until she defeats Lancer and lifts the curse on her hand. It’s just as well that Berserker withdrew when he did, as a longer confrontation might have killed Matou, who vomits blood and worms in a dark alley, but remains as committed as ever to protecting Sakura by winning the war.
What of Uryuu and Caster, the only Servant who wasn’t on the field? Bluebeard observed everything from a crystal ball, and has taken a particular—and worrying—interest in Saber.
