Well, there's the axe coming into play, Kanan thinks, just after Hera moves on the startled Gamorrean.

Then he hauls himself to his feet, flipping the table so it functions as a bulwark between Hera, himself, and Fortuna's crew. Hopefully this'll give them time to get out of here, but first -- disengaging from combat in general.

Fortuna is still snarling, spitting out commands to his bodyguard, who is bleeding into his own eyes. "You fool! What do we pay you for? Get her!"

But at the same time, he's also closing with Hera, because otherwise he'll lose face, and that . . . might end poorly. (Or so Kanan assumes, knowing what everyone does about Hutts.)
