I never guessed what crest Sora had until she said it herself. I was thinking like Tai: wow, the crest of love; that's just perfect for Sora!
If it weren't for Sora, TK and Tai would probably be brain washed right now, and everyone would still be split up. I wonder if Mimi would still be Princess in the castle if Sora hadn't been there when she woke from her dream. Without Sora, they probably would be split up in the digital world forever.
Sora has the crest Love the best quality a person could have compared to faith and hope. Love is patient and kind, and so is Sora. She's always caring about the rest of the group and loving Biyomon. Read more about the crest of love under love on my digivocab page.
