[X] Okay, you have to admit you're curious as to why Ardat is acting so strange towards you now. Go talk to the Witchmon and try to find out what's gong on with her. Plus it's been a while since you've really interacted with the eccentric Witchmon. In a way she has grown on you... maybe like a kind of moss?
[X] Studying your current spell shouldn't count as training right? Your current progress has been quite relaxing, and you've made a bit of progress, but you can always do more! Sure you won't be finishing it anytime soon, but every bit of progress counts if you want to be able to use it someday.
[X] Ask the other Pidmon about what happened on his mission. From what you've gathered he was part of at least two others squad's before something bad happened. Angewomon got hurt so badly she devolved into a Darcmon (you think) and the rest of his fellows were deleted. Something must have gone wrong.
