This just in: The Riley

The Riley: More potent in or around bodies of water; tries excessively hard to hide true identity, but is unmistakable. Recently has tried to force itself on everyone all the time.

This just in: The Alex

The Alex: Unpleasant, caustic, and sour but with occasional unexpected bursts of sweetness.

This just in: The Darcy, The Liberty

The Darcy: You might think it comes out clean, but upon closer inspection you'll find it's dirty as sin.
The Liberty: Always does the job when you need to clear a room in a hurry.

Honorary Mention

The Kevin Smith: A breath of fresh air when it first bursts onto the scene, however once it stirs up trouble for other people it rapidly outstays its welcome. Beware: this one's usually silent.

This just in: The Clare

The Clare: Silent, stealthy, and dangerously underestimated.

This just in: The Ellie

The Ellie: Rather depressing, like the sound of a balloon slowly deflating.
