With a big thanks to kennywr22 for pointing out that the MSN TV Listings have been updated with a bit more info on G.I. Joe: Renegades episode 5.  “Return of the Arashikage Part 2” has the following description:

“The team regroups and hunts down their attacker.”

Thanks to TVGuide.com, though, we get even more details, including a surprise guest star!  I have put it after the break for spoiler purposes, so click the “Read the Rest of this Entry” link below for the full skinny.

While MSN.com does a nice succint recap, the TVGuide Episode Page for G.I. Joe: Renegades gets into even more detail.  Here is the snippet:

“Conclusion of 2. The Joe team regroups after an ambush from Storm Shadow. Now they must come up with a plan to rescue Jinx, who has been kidnapped.”

That’s right, Joefans, Jinx is making an appearance in G.I. Joe: Renegades!  Not only that, but we get confirmation of an early appearance of Storm Shadow.
Now astute Joefans who have been paying attention to the JoeCon coverage I provided saw that the producers mentioned a certain “bad luck ninja” making an appearance, so you shouldn’t be surprised.  But now we know when and where.  Bring it on!
