Daredevil (vol 1) #108 VG/GD

Tensions between Black Widow and Daredevil heat up over the Christmas holiday as Black Widow presses Daredevil for answers about his feelings about Moondragon, and unfortunately he doesn't have any to give. Their talk of relationships ends abruptly when they witness a gang of thieves trying to mug an old lady. The two heroes swing into action, and easily take them down. Natasha takes things too far and is pummeling a man near to death, and Daredevil is forced to strike her in order to make her stop. When the police come to arrest the crooks, and Daredevil is thanked by the old lady, he realizes that the Black Widow has already left.

Traveling back to the mansion where they live, Daredevil gets into an argument with the Widow over the ethics of brutalizing the crooks they fight. When it seems neither side can agree, Daredevil stops the conversation and goes downstairs to Ivan and Moondragon, who are decorating the place for Christmas. When Ivan turns on the TV news a report comes on about how Foggy Nelson was shot by an unknown sniper and is recovering in hospital. Matt is instantly worried and begins making arrangements to get to New York. Matt's request for Ivan to make travel reservations for him and Natasha is quashed by the Black Widow, who refuses to go to Foggy Nelson's aid especially after he had her tried as a spy in court. Moondragon offers to give Matt a lift in her spaceship instead and Daredevil rushes upstairs to pack and is ready to go in a few minutes. With Daredevil gone, Black Widow breaks down in tears and admits her feelings for Murdock to her bodyguard Ivan and fears that she has lost him for good.
