 Both characters display sadistic tendencies, in that they are equally likely to take pleasure in tormenting each other, although it is often in response to a triggering event.However, when one character appears to truly be in mortal danger from an unplanned situation or due to actions by a third party, the other will develop a conscience and save him.Occasionally, they bond over a mutual sentiment towards an unpleasant experience and their attacking each other is more play than serious attacks.
