A woman in the water, mid-swim, with her mouth wide open as if she's trying to catch both the tide and the words escaping her mind. She's caught between the chatter of the surface and the quiet murmur beneath the waves, like she's speaking to the sea as much as herself. You'd use 🌊 for the water and 💬 for the talking together, they're perfect for someone deep in thought but not done talking yet.
