Tonight, Aquile faced his biggest challenge on NBC's "The Voice" to date - the new "knockout round", where in one competitive night, half of Team Christina went home, prior to the live shows.  Here's how Casper's favorite singer fared:

Aquile was paired last by coach Christina Aguilera, to face fellow singer Sylvia Yacoub.  He chose "Grenade" by Bruno Mars, up against Sylvia's version of Coach Christina's "Fighter".  Unfortunately, when the final decision was made - Aquile's "Voice" journey ended tonight, which means that he won't be moving on to the live shows.  While we were hoping he'd make it through to the next level - we're convinced that this won't be the last you hear from Aquile.  As a matter of fact, he's got another Casper appearance on the way soon, where we'll be catching up with him again to get the latest scoop on what's next for this promising Wyoming singer.
