The Joan of Arc mentioned by Artoria [Alter] was worlds apart from the Joan of Arc Luo Zhen knew.
Thus, Luo Zhen couldn't help wondering whether Artoria [Alter] had encountered a Servant impersonating Joan of Arc.
It wasn't all that unusual, either. Even Serenity possessed ever-changing appearances and could transform into anyone of a similar build. So, having a Servant take on Joan of Arc's appearance and impersonate her identity wasn't difficult at all, was it?
In any case, Luo Zhen absolutely refused to believe that the Joan of Arc Artoria [Alter] had mentioned was the same person as the Joan of Arc he knew.
Therefore...
"No matter what, let's go confirm it first."
Luo Zhen spoke up.
"I'll make a proper judgment on whether the other party is worth saving."
His words also served to reassure Artoria [Alter].
Otherwise, Her Majesty the King of Knights would have left without hesitation, without the slightest reluctance.
Sure enough...
"...Since that's the case, let's go take a look, though I really don't want to."
Only after saying that did Artoria [Alter] finally give up on leaving.
Luo Zhen then looked toward Serenity, who had been silently nestled in his arms. For some reason, her pretty face was still flushed, and she seemed faintly happy.
"You know where Joan of Arc's cell is, right? Can you lead us there?"
Luo Zhen asked.
"Yes, of course."
Serenity was as obedient to Luo Zhen's words as before—so obedient that she was far more compliant with him than with Artoria [Alter], the king she had sworn allegiance to. It made one wonder whether the king this Hassan served was Artoria [Alter] or Luo Zhen.
But regardless, having an obedient Servant was far better than having a Servant with an overdeveloped sense of self who ran wild
