"I don't need to defend myself in a fist fight. I can bench press a truck." Astrid sighed miserably before throwing out a left hook that caught the bag and ripped the hook from the ceiling, sending the bag crashing into the wall and damn near through it. "I don't know what I'm doing here. I don't belong here." She sat down next to her dog on the floor, petting the furry creature as she watched Steve work out. She had seen him faux boxing with a few of his fans in the parking lot a time or two but she'd never gotten to really watch him throw a punch. He wasn't bad. But she found herself zoning out and calculating everything about his moves in silence, deducing that she could take him down. She hadn't seen Thor or Hulk fight before but she knew their strength was more on par with hers. Still, she was thankful that Captain saw [i]something[/i] in her. She just wasn't sure taking his offer was right after turning down her friends.
