[Spoiler] Did they forget Porxies exist?

[No_Nick_Needed]

When we met the child oversaturated with lightning eather, did the writers forget, that we've already cured this?
With Angelo and his fellow Porxies, we cures light-overaspecting in the First and various elemental oversaturations of tempered in the Source.
To me it sounds like pretty much the same issue, he's essentially a tempered without a master, in a manner of speaking.
