In some cases, Dante could distance himself from Nero for a while. He might go off on his own to cool down and think things through. Meanwhile, Nero could be left feeling guilty or confused about why Dante got so angry.
One possible reason could be Nero's over - eagerness or recklessness. Maybe Nero keeps getting into dangerous situations without proper planning, and Dante, being more experienced, gets pissed off at Nero's lack of caution.
