Thor: The Dark World actress Jaimie Alexander donned her Sif garments again recently on a trip to Children's Hospital Los Angeles, spending an afternoon visiting with young patients. Marvel.com has posted a massive photo gallery of Alexander as Sif with many patients and staff, who were able to pose with the Asgardian warrior and in some cases, even hold her weapons. The actress also gave out signed Thor DVDs and posters.
