Then again, power of friendship or feelings is something of a commodity in FT so would makes sense that more of the super-secret-complex-no-one-can-ever-do spells/powerups or whatever are just variants of PoF cause that's pretty much how it has been for FT. Would be nice if that wasn't the case, but who knows. Maybe Zeref decides that his demons require the power of feelings as well and that Minerva is quite a good addition to have while Marde is an old experiment.
