Rafe, Ellie, Heather, and OPEN
Heather bought out all her challenges outside of one, and even that she had to consider seriously. She was terrible in cold weather, hilariously so considering she went to school in Maine and now lived there, but she was used to the beach and sunlight. She cheated a little and was wearing several heating enchantments, masquerading as a simple necklace and bracelets. No one said she had to freeze to death for charity, so she would stand by it. She was otherwise in a simple swimsuit which was basically what she wore as swim coach.
She overheard Rafe's offer as she passed by, not really intending to eavesdrop, but it was the type of thing he would do. She was intentionally ignoring the fact he was wet, and that she was wet, because that was the type of thing friends did. Friends who were exes. Heather smiled and slipped one of her bracelets off, offering it to Ellie. "Trade secret," she stage whispered at her. The warming enchantment wouldn't make her immediately heated, but it would take a lot of the bite out of it, and the blue from her lips. It explained why Heather was chilly but not freezing.
She wrung out her hair. "This is not something I missed," she remarked to Rafe, but it was in a good natured way. Otherwise she wouldn't have done it at all.
