[Terpsichore]

This is how the average odds have changed over the last three days:

Twins 1.33 1.32 1.29
Brian 3.32 3.33 3.57
Liam 12.90 13.27 20.0

Twins odds continue to shorten, Brian slips slightly, Liam slips drastically.

Liam is the surprise. I can't think of any reason for his sudden decline.
