Or Drakul made a huge mistake by doing that,when he tossed Chandler through that portal, he in effect he threw the rabbit into the brier patch.
If Chandler were a Michael, or Butters, or someone who's been around a lot, I could see it. As he is right now? I don't see it. I see him either being an enemy in plain sight, or now a slave of Drakul.
Either he got Carlos to assign him to the mission, or Carlos was manipulated into bringing him, in my opinion. I believe Drakul wanted Chandler specifically which is why he wasn't killed like the others. Either way, it wouldn't make much sense for Drakul to get him, only for Chandler to sneak away on his own. If he does escape, it's because Drakul wanted him to (let him go). Remember him mentioning that he sometimes promises people immortality? Hmmmm
