What Does "This House Is Bitchin'" Mean on 'The Flash?'

On tonight's season 4 premiere of The Flash, Cisco decoded what he was certain was an important, coded message from Barry -- but it turned out to be something apparently random.

"This House is Bitchin'," read the message, decoded from a cypher Barry had been scrawling all over the place.

"That doesn't sound like Barry," Team Flash decided, and Cisco resigned himself to the probability that Barry's brain was damaged and he was lost to them.

...But what if that's wrong?

"We'll see kind of the effects that the Speed Force has had on Barry," Gustin told ComicBook.com this summer. "He's been in there six months real time but the way I se it the Speed Force is non-linear with time, so Barry has experienced his whole life start to end infinity times over since he's been in there. He's going to have kind of an awakening when he comes out; he's got some knowledge that he probably doesn't even quite understand yet."

So -- what if everything from the comments about being innocent to the comments about diapers to the comments about his mother and, yes, even "this house is bitchin'," is important somehow?

It does not seen particularly farfetched, since fans already know that "I didn't kill anyone" could be about "The Trial of The Flash," while the diapers comment could be about the Tornado Twins.

The Flash airs on Tuesday nights at 8 p.m. ET/PT on The CW.
