Not quite Walter

A naked blonde teenage girl was floating lazily in the pool, her hair fanning out around her like a halo. Frank blinked, taking in the scene, his mind struggling to process what he was seeing. He had been expecting Walter, but this... this was something else entirely.

The girl noticed him standing there, staring, and leaned over the rim of the pool.

"Hey, Frank! Glad you finally made it!"

It was then that Frank realized something was profoundly wrong. That voice—it was unmistakably Walter's, deep and gruff, coming from the body of a teenage girl. He shook his head, trying to dislodge the confusion.

"Walter?" he asked hesitantly, stepping closer to the pool's edge.

The girl grinned, her eyes sparkling with mischief. "In the flesh, so to speak," she said, her voice still distinctly Walter's. "Or should I say, in someone else's flesh?"

Frank stared at her, then at the house, then back at her. "What the hell happened to you?" he managed to ask.

Walter—now seemingly trapped in a teenage girl's body—laughed, a sound that was entirely at odds with his usual demeanor. "It's a long story, Frank. But I could use your help!"
