Where in the world is Carmen Sandiego Cassie?

Her boyfriend Anthony knows but -- on Wednesday’s episode of MTV Suspect -- he realizes at least one of her colleagues most certainly doesn't.

In a sneak peek of the show, below, Nev Schulman and iO Tillett Wright urge Anthony -- who's worried because his other half has been acting "a little differently" -- to place a call to James, a "really good friend"/coworker of Cassie. So what does James have to say about their relationship?

"Since Cassie's been in China, we Skype occassionally," he begins.

Cue three jaws dropping to the floor.

"Uh, what do you mean she's been in China?" Anthony asks as he, Nev and iO share looks of bewilderment.

That's not all: James reveals he hasn't actually seen his friend in over a year -- save for those once-a-week Skype sessions that are often interrupted because "the internet connection in China is a bit spotty."

Sounds ridiculous reasonable to us.

So what excuse did Cassie give James for supposedly being on the other side of the world? Watch the clip to find out, and to discover what's really going on with her, catch MTV Suspect Wednesday at 11/10c (right after Catfish)!
