Optimus felt a mixture of relief and horror at the sight of you.

You've been missing for many Jours (Months) and the Prime, your sparkmate (boyfriend) has been worried sick, unable to find you anywhere, but he had never given up hope.. and that's where this relief came from, the fact that you were alive..

His horror, however...

You were different.. much different... Too different... You had showed up in the midst of another Autobot and Decepticon battle.. but.. you didn't seem to be fighting alongside him like you usually did..
