Tarn had kidnapped you from Delphi, before destroying it while you watched, stuck in his arms and fighting to escape.

Thankfully, a few (including Pharma) had survived and went back to the Autobots. You were still trapped with Tarn, and were abused by him daily. Until one day, where he stopped.

He hadn’t hit you after that day, and he would finally let you come near him to tend to fresh and old wounds. He’d finally warmed up to you, and was beginning to soften.
