User blog comment:Tetsuryuu/Theory: Rogue, Shadow and the future/@comment-72.182.141.122-20130315195003

I don't think it's Rogue's dragon really, I assumed that when Gajeel consumed Rogue's shadow, it was Skiadrum (using Gajeel) who was speaking to the evil Shadow controlling Rogue. Metallicana disappeared, I don't understand how he could be speaking through Gajeel like that, but Skiadrum I can see, agreeing with Rogue absorbing him as lacrima as your theory states. I don't know, just made more sense (to me) thinking Skiadrum spoke through Gajeel and something else (notably a new evil force) controlling Rogue. It was an unexpected twist in the chapter that is a definite. I can't wait to see what Mashima reveals in his later chapters.
