At first glance, I thought it was a joke about a difficult step in the toy's transformation, but I recall Armada Starscream's hands being easy...in fact, the whole voyager-size toy was pretty easy.
I guess it's a nice stab at rationalizing why he couldn't just fly out; could 'Cons just fly in robot mode in the Armada comics? I don't recall them doing so, but it's been many years.
I was hoping this would tie into stuff his Energon ghost did after Dreamwave went bankrupt. (has someone done fan art of him sneaking up behind Pat Lee instead of Overrun, ala that cover of #31 or 32?)
Much as I want to like all of the last Mosaics before project's end, this one could've used a little more...something. Still, it was nice to see a Unicron Trilogy one for the first time in a while.
