Shield
When Natasha arrived with her sword in hand, Sif was already shouting at Hogun. "Get off my field!" She punctuated the decree with several warm curses and a slashing blow at the warrior's buttocks.
"Hey, hang on." Natasha said. "What has he done that is so dreadful?"
In a fury, Sif rounded on her. "And why are you interfering? By the gods, I have had it up with well-meaning, clumsy fools who cannot wield a spear if their lives depend on it!" She went on like that for several minutes, during which time Hogun sidled off and took to his heels when he was far enough away.
Natasha merely listened patiently, her arms folded and head tilted. At length Sif ran out of steam and flicked her eyes up and down. "And what are you looking at?" she demanded.
"Someone who's so unhappy she insists on picking fights with every friend she has."
Sif opened her mouth to shout further, but at Natasha's straight look she stopped and slashed the turf at the feet. "I wish…" she began.
"I'm going to take a trip to Midgard," Natasha said suddenly. "You should come along."
Sif held up her shield as though she could ward off Natasha's words, but the Russian merely laughed and pushed it aside. "Come on," she insisted. "We'll go shopping, and I'll show you Stark Tower."
"Shopping? For what – shoes?"
"I was thinking weapons, but shoes are good too." Natasha grinned. Mentally, she prepared to tell Loki he had to come as well; later they could all go dancing.
Maybe Steve could join them.
