Headcanon #3

Reiner has never seen Bertholdt angry before and feels both curious and anxious for the day to come where he gets to witness the tall man’s rage. Sometimes curiosity makes him tease and argue with Bertholdt to see what happens, but it usually leaves them with awkward silence or Bertholdt near to tears asking Reiner what he’d done to make him angry. Reiner then realizes, with a remorseful sigh, that Bertholdt doesn’t even know what true anger contains.
