I dunno if this has been brought up before, but a thought struck me: What if Skids and Mudflap now share the same symmetrical Alt-mode so that they can combine into a larger robot-mode ALA the Jet-Twins/ Safeguard from TFA? Furthermore, Bay said the "Twins" won't be in this movie... what if he means they won't be there individually, but as one LARGER being? Think about it- they both even have the large "murder arms" on opposite sides of their bodies!!! It's fun to theorize- after having seen the "Twins-to-Shockwave" concept during the movie-fanart contest, and taking note of their DARKER color scheme, mayhaps they are Decepticon spies afterall? Give them a name like Doublecross, or Sinnertwin!
