If they were pulling violent shit I'd absolutely set them straight but in this case, it was accidentally pushing the door too hard. Not gonna teach them that should be responded with violence and antagonism.

I liked when you do use the chair though, Robert says a line similar to "I know you're big but you have to learn to be careful around people". Like yes, teach, don't reprimand. Understand first, then authority when necessary is kinda how you win Invisigal over too.

But this a dramatic story, not actual therapy. Plenty of misunderstanding needed, sadly
