Does anyone knows what chapter Claude will finally have his memories back?

I'm not really sure when because some parts of the Manhwa is different from the novel

(SPOILER ALERT!)

In the Original Novel of WMMAP, Lucas stabbed Claude with the World Tree's branch to make him regain his memories, I'm not sure when cause Lucas was supposed to be back at Athy's 15th Birthday

I also heard that Spoon said that there are only a few chapters left about 20-30 chapters left （￣へ￣）I still want more though
