Pardon the delay. Anyway, it'd take some time to get a transcript, & I'm a little distracted lately, so for now, I'll just link the pages I feel are relevant & try to provide some commentary. I'm sure capable users can also provide translations, if need be. (Sorry about any inconvenience.)
Start of chapter, page 45:
http://jb2448.info/picture.php?/20857/category/1878 (I THINK the last at all relevant (for our discussion.) page to the chapter is
page 59 , as Mew appears in the sky in the background.)
Page 46 has some set-up & a little discussion about the area the protagonists go to.
Pokemon spirits seem to appear.
http://jb2448.info/picture.php?/20858/category/1878 http://jb2448.info/picture.php?/20859/category/1878 They seem to have some bad feelings regarding humans, & one of our protagonists hears quite a bit of that, I think. Page 48 is also when the entrance -some sort of portal- to what I believe is called "Mew's Forest".
Pages 49, 50, & 51:
http://jb2448.info/picture.php?/20860/category/1878 http://jb2448.info/picture.php?/20861/category/1878 Our protagonists, along with their Pikachu & Squirtle enter.
http://jb2448.info/picture.php?/20862/category/1878
Page 52: What appears to be Mewtwo & with warnings to the intruding humans.
http://jb2448.info/picture.php?/20863/category/1878 Almond (the boy) wonders if Mewtwo created an exit. Around the last panel, after the warnings & Mewtwo's departure, the snow begins to fall.
Page 53. Story continues, the snow has already blanketed what of the forest is shown. Marron (the girl) seems to be thinking that at this rate (My translation isn't perfect, so I'm not sure if she means about the rate of snowfall, or if they keep exploring.) they'll freeze to death.
http://jb2448.info/picture.php?/20864/category/1878 I'm also not sure of the timeframe, unfortunately.
Another appearance by Mewtwo. I'm not sure if it's not a flashback or such, given the slightly different dialogue, but there's also a lack of sound effects indicating it showing up, & I'm not sure context suggests against it being a flashback either.
http://jb2448.info/picture.php?/20865/category/1878 Also, Almond tells Pikachu & Squirtle to help out. Although I'm not sure what they do, given that it happens off-screen/between panels. In any case, our protagonists take shelter in a cave.
Page 55, & 56.
http://jb2448.info/picture.php?/20866/category/1878 http://jb2448.info/picture.php?/20867/category/1878 After some thought about their friends & concern, Pikachu & Squirtle run out of the caves to protest, in praise of their trainers, how they're their friends, & not all humans are bad.
Page 57: In response to all that, Mewtwo appears, seemingly with a "sad look" on its face.
http://jb2448.info/picture.php?/20868/category/1878 Mew is then sighted. At the end of this page (Bottom left corner.) a sound-effect like
ÒâûÒé¬ appears.
A somewhat similar sound effect appears at the start (Upper right corner.) of page 58. The fact that Marron states that where they are now is just outside her house suggests to me they were teleported, but it may be up to interpretation. Also possibly up to interpretation is some dialogue between Marron & Almond if Mew really was there, if it was Mewtwo's power.
Finally, on page 59, Mew appears in the sky in the background.

As far as I can tell, the other pages aren't relevant to this story. Sorry about the messy format. Later, I can probably get to typing up some transcriptions for this thread, but I'm sure more able translators could provide quicker & more reliable transcriptions & likely translations as well, so any willing to help would be appreciated.
Hopefully this helps you all evaluate this stuff, & sorry about being so late getting around to this.
