Learn where to stop

If you think you could make Tom smile, tell him some jokes~ perhaps he will.

If you think you could stop Grey from thinking, try to understand his steps and show him love. It might work.

And that should be enough. Just stop right there. If you think you could make Swalk bow down for you, you'll only end up crushed by his juggernaut anger. Know your own position. If you're able to summon him doesn't mean you're someone powerful enough to order him.
