The Gator lunges forward, jaws flashing, and slams into Kaspar!

All out of momentum.

The beast is dead. Well done. Kaspar hears shouting coming down from the manhole. But he does not have time to respond just yet. I am assuming that you are running over to Castille and pouring Castille's cure light wounds potion down the half-elf's throat. (DM rolls) Castille is now awake and has 2 hit points. (Note that Kaspar still has a cure light wounds potion.) The one casualty is Castille's sunrod, which shattered from the Gator's blow.

Strong hands belonging to watchmen and Scowlen help you haul up the two workmen's corpses, and you hear the weeping of spouses. Do you want to bring the Croc corpse up as well?

Whatever you do when you go up, make a Sense Motive check regarding each person you talk to. A Diplomacy check DC 8 will get Scowlen to cast enough cure spells to bring Castille back up to full. An even higher Diplomacy check might get you more equipment from Scowlen.

And of course you have that evidence to show. And since Sgt Einian has the Investigate feat, he might find out some more clues from the bodies that you could not.

So: Decide, type, roll, and post.
