fringe snakehead

Supernatural and TheThe Vampire Diaries are on reruns tonight, but Fringe and FlashForward are all new. Here's a look at Thursday's sci-fi TV:

Fringe, "Snakehead" – The team uncovers another bad batch of crazy when a cargo ship runs aground, spilling out dead bodies hosting giant squid-like creatures. Walter allows one of the parasites to feed on him and finds the experience "rather pleasant," while Peter, Olivia and Broyles learn the case has ties to a threatening organization (maybe Massive Dynamic?). (9 p.m. ET on Fox).

FlashForward, "A561984"
– For those still keeping track, tonight's the night that Lloyd's organization reveals their involvement in the blackout, while Mark and Demetri head to Hong Kong in search of clues to Demetri's futuredeath. (8 p.m. on ABC.)
