What?  Since when can Isla enter her own paintings and use them as a travel medium?  If she somehow put herself into a painting (the spell reads 'The user slams a canvas onto the opponent their head and the opponent will find themselves in the canvas' by the way) wouldn't she kill herself if she destroyed it?  When Indigo found Ike's painting, Isla said that destroying the painting would harm Ike, right?

I find it to be dubious that Isla exhibits the power of paint-traveling even though it's not mentioned in her sheet when it seems convenient.  Even if the plot justified it, wouldn't it be better to get her involvement with Frenzy Plant finished rather than put off?  I was thinking that if she apologized to the members and cooperated, Sanders would probably let her off easy.
