Not sure if this is a mistake on the guide's end or something wrong with my game but the lady in the flower shop won't tell me about the Budew password when you mention it. I don't know if there needs to be something else that happens before but even with messing with the switches and variables needed it doesn't happen.
The Nincada encounter in the Byxbysion Wasteland should be bolded since that's the next available chance to catch it after the egg from Malchous Forest. The same can also be said about the Panpour and Pansear encounters in the Spring. In your strategy talk for the Rime badge you say that we have access to the Wide Lens when I think you meant Zoom Lens. In the Tanzan Depths the Geodude and Graveler that you find are their Alolan variants.
I know it's supposed to be like a 1/10 chance that the blitzle is actually a wimpod but since we have the mono passwords shouldn't the bug and water passwords change that event as well?
I don't know about her other pokemon but Marianette's Bewear has brick break instead of drain punch. You also have an unfinished sentence after the event with the Throh.
When you first mention the "high" and "low" trees on route 2 you say that the right tree above the bridge is a low tree and the left one is a high tree when it's the opposite.
