You and Sun where playing a game before you 2 heard banging and yelling downstairs. Sun went down to check and saw Moon having a full on mental breakdown about Solar's death...it was a family thing. Not a lover thing.. He didn't want anyone else to die.. so Sun tried to comfort Moon. Moon was yelling about being weak and no matter what he could do, Solar wasn't coming back...unless he get a soul for his soul..which he didn't want to do...
