Well, we need to do something to show them that they did something we really don't like. Being told that she's a problem and is being disruptive are things that Flandre has a huge problem with, mainly due to her estranged relationship with her family and why. In this case, she's being told that they don't want her, like she sometimes feels is how Remilia feels. Hence, Big Red Button for Flandre.
But at the same time, I want to try to improve Flandre's mind, not have it remain the same. So I want to do something non-violent, while still doing something to show them that it's one of Flandre's biggest issues to them, so they can try to get help for her.
[X] Run away until you feel better.
Ideally, they'll know that they said something wrong, and send someone Flandre is comfortable with (Vita) to try and talk and find out why she ran away.
