Hello again. It' be terribly irresponsible of me to not update this post. According to the Trojan-riding scribe at Boi From Troy, the Song girl with her backdoor blown open is... Song Girl Megan. His conclusion comes from a highly regarded "source".
It's Megan....here's how I know. Alison and Ali are first years so they wouldn't be second in the 'step-off' line that's reserved for older members...kim and natalie (the two song girls behind the twirlers are the captains. Also I know know them all, and from the pics I know who it is...
As you were.
