There really wasn't much to discuss.
The Einzbern Family's stronghold was in that location; there was no other possibility. After all, it had been confirmed that the Einzbern Family's castle had been activated.
As long as the two Servants joined forces and fought at full strength to restrain Berserker, whatever came afterward would be manageable.
Leaving Shirou Emiya behind to rest in the room for the time being, Anno and Matou Shinji headed together to Adelson's Magic Workshop on the third floor.
"Allow me to greet you once again, Mr. Saber. It has been a long time."
Matou Shinji solemnly greeted Anno.
"And I must also thank you for ultimately eliminating Archer Gilgamesh in the previous Holy Grail War."
Matou Shinji's decision to dissolve his contract with Archer during the previous Holy Grail War had actually been a very risky one. Based on Archer's performance in earlier Holy Grail Wars, as long as Archer did not fight too recklessly, his capabilities as a Servant would never have been inferior to Saber's—he might even have surpassed him.
If he had dissolved the contract only for Archer to bring out some unprecedented Noble Phantasm or method and defeat Saber—then he would never have been able to complete his revenge or stand up for Sakura.
Fortunately, Anno's strength was trustworthy. In the end, he completely suppressed Gilgamesh and successfully sent the King of Heroes back to the Throne of Heroes.
"No thanks are necessary. Even if it were not for the Holy Grail War, I would still have had to kill Gilgamesh."
Anno sat down in a chair.
"This time, it was actually my ancestor who wished to meet you."
Matou Shinji stepped aside, allowing Adelson to come forward.
".Mr. Anno, are you... an end cut from the Thread of the Root?"
Adelson
