the guy with the eyeball was in conspiracy with jason. he said jason told him to give them a message with an eyeball.
Haha. Like many things in the F13 universe, that's open to interpretation... but... the general feeling is that Abel is a "wacko" who probably found a body part and felt it was a "sign" from Jason in his mind. The reality is, if Abel and Jason had crossed paths...Jason would've just killed him instantly - he certainly wouldn't have introduced himself, gave ol' Abel a pat on the back and said to him "Go tell them about me".
