There are four bachelors left on this season's "The Bachelorette," and tonight, Jillian Harris jets off with them to Spain, where Wes makes a slip of the tongue that may show his true colors!

Jillian meets up with Wes in Barcelona. He is his same irresistible self, and they bicycle through the city. But, the Canadian cutie becomes concerned when he doesn't demonstrate any real affection for her.

So, that night at dinner, she asks him to tell her what is what, and, in attempting to do so, Wes misspeaks -- or does he? This leads Jillian to tearfully confront him with her worst fears.

"The Bachelorette" airs tonight at 8 p.m. on ABC.
