Last summer my 11 year old daughter wanted to take a picture with Alice so when we got to the front of the line Alice asked her to show her her backpack... so my daughter took it off and showed her and Alice snatched it out of her hands and ran into the garden area of the UK pavilion and shouted out 'you can't catch me!' and my daughter chased her around all over the garden...she seriously didn't budge, made my daughter chase her all over! It was so funny and sweet. My daughter loved it. A great memory. My guess about Elsa is that she's probably wearing the 'gloves' in the park and her answer might be 'I cannot show my ice powers with my gloves on, remember?' and then swiftly change the subject...I'm not sure, but that's my guess.
