is one piece episode 608 filler?

Law walks into the SAD production room, looks up at the giant tank, and smiles. Meanwhile, the Marines are crushed that the shutter closed, trapping Sanji and Vergo in with the gas.

Someone tries to make an announcement about Law over the PA system, but the Marines are distracted as Sanji has appeared above them carrying two unconscious Marine soldiers. Sanji is happy to see Tashigi and tells the other soldiers to shut up, saying he only likes it when girls cheer for him.

He takes a step and winces in pain.
