So, I am most probably wrong, but with the release of MTMTE 16 last week, and Rewinds posthumous declaration of love for Chromedome it occured to me, is that the first time that we've had Transformers tell one another "I love you"?
We've had official 'couplings' before, I suppose (such as Airrazor/Tigertron), but I don't remember them every actually addressing it in story, and, you know, I'm sure there's some familial Transformers which would have a strong connection to justify it, but have we ever actually seen Transformers declare things like this before?
Are Chromedome and Rewind not only the first gay TF couple, but the first Transformers couple to actually vocalise how they feel with those three words?
