If Shard were to be threatened he'd go into a rage and attack, or stay calm and tell you to chill out. There's no in between.
If Immortal were to be threatened she'd curse you with being haunted by your own shadows for all of eternity. There's a high unlikelihood that you would survive a day.
If End were to be threatened he would stay calm but if you are persistent he'll fight.

(There's no example, sorry!)
