Sundering stuff established in the Q&A

[polyphonica]

Small correction, the french version highlights that when he says this, he's meaning getting to Ultima Thule. Not anything else.

Honestly, I would say that the Japanese is quite the opposite. A more literal translation of his Japanese line would be "Still, the fact that humanity has gotten this far... It's true that this result could not have been achieved by our methods." The context for this line is all the pain and suffering he had to endure, so Venat will get no thanks for the part she made him play in it. And in the Japanese it's not pointed at the WoL specifically, but that "humanity" has gotten this far.

If the French translation is more specific here, I think they made an inference that wasn't present in either the Japanese or English versions, and may have slightly constrained the meaning of the line.

Edit: For whatever it's worth, here's the original line:
……しかし、人をここに至らせたこと。
この結末は、確かに私たちのやり方では掴み得なかったものだ。
