Tackle hoods.

The stranger briefly smiles his thanks, then ducks swiftly aside as a thrown dagger scythes where his head just was. The two thugs are upon you in a moment, but despite his bad leg your new-found friend is surprisingly able. He fells one of the hoods with a low blow followed by a chop to the neck, but the other is bigger and heavier and lands him an elbow to the temple. You stamp on the attacker's knee and momentarily unbalance him, giving the stranger enough time to pick up a piece of nearby debris and whack him in the kidneys. The big man staggers forward stunned, crashing awkwardly into you and propelling you backwards against a wall.

Your head strikes the bricks and everything goes black...

Regain consciousness a few minutes later.
