he has to clean out the semen

Bit of backstory, we just finished up a major story arc and or fighter has just been given a package with what seems like his tattooed fathers cut off hand. 

Fighter: “I don’t know what you guys are doing but i’m going to go find him.”

Paladin: “Remember our enemy has used misdirection on us before. We should try and see if the hand is genuine before setting out." 

Paladin (ooc): "We need to Pathfinder CSI this. For example is the ink more bold or faded, if they tattooed a random hand. Is the cut clean like he was held down captured, or more jagged like it was lost in a conflict and he may still be free. How much semen is on the hand, ect. You know, the regular CSI questions.”
