The season finale of Fringe airs tonight on Fox, and judging by this new preview clip, the action picks up right where it left off last week—essentially with all hell about to break loose.

Peter and Olivia stumble into Walter's eerily empty lab, with Dr. Bishop and Astrid still missing. Considering Olivia's super-powered show outs in recent weeks, Peter tries to broach the topic in the meantime, with limited success.

Regardless of how the finale plays out, at least we know it won't be the last we'll see of J.J. Abrams' little sci-fi series that could. The show has already been renewed for a final, fifth season.

So, sit back and enjoy.
