Kjula looks at the distant figure of the lone goblin, feeling that he's going to go away. That he'll carrying the axe with him feels less disturbing than he doesn't know how or why did he risk so much with such bold attack.
Then the other goblins appear below the bridge – they must obviously be in league, and can be interrogated to know where the thief is going. They are close, too, but the terrain isn't very good for his style. The bridge looks like a good place to hide behind and from where to ambush the goblins.
With such reasoning he dives into the river, trying to be as quiet as possible. The cold water nearly paralyzes him, though.
[sblock=mechanics]Well, two great rolls. I intended to move into the river with one move action, then swim down it and let it carry me along while trying to be as less visible as possible – I don't know how clear the river is, or if it's possible to remain out of sight by keeping most of my body underwater, but I rolled stealth just n case it's possible[/sblock]
