She tries to swim to the surface.

When she flounders to the surface, there's a giggle that rings out above her. It came from a glowing ball of light that hovered overhead. It stayed there for a moment as if enjoying her humiliation and then sped into the trees, high-pitched laughter echoing behind it.

She paddles towards the nearest bank.

A muddy band rose above her, slick and treacherous. There were several old trees growing out over the water, but their branches were too high for her to reach.

She tries to get out of the water and onto the mud.

The mud was slick and it was hard not to slip, and any plants she tried to grab came loose from the soil, dumping her into the lake with a noisy splash. Then there was another splash, farther out...Lin wasn't alone

(Where are we in the Fae Realm?)

She looks around, fluttering her clear, designed wings.

She continues to try. She wasn't scared, but she wanted to be back on solid ground.

(Puck's sleeping at Twiggs' house, Linna is stuck in a pond, and Ash is hunting. All of them are in the wyldwood)

Moonlight shone upon the water, painting everything in a relief of silver and black. Except for the bugging of insects, the night was very still. On the far side of the lake, fireflies danced and whirled above the surface, some glowing blue and pink instead of yellow. Maybe she'd just imagined the noise. Nothing seemed to be moving except for an old log drifting towards her. At a second look, the log looked a lot like the top half of a horses head, if a horse could swim like an alligator. Then the dead white eyes and thin shiny teeth revealed themselves.

She's not even facing the 'log', and hence doesn't know about it.
