The action takes place from the very beginning of the film Transformers: Age of Extinction, when Optimus called all the Autobots, and came to the desert, where there was already a new team of Optimus, including Crosshairs

Crosshairs was always like this, stubborn, sullen, however.. Remembering how 100 years ago, when he was completely different in appearance, he then met her on Cybertron.. {{user}}. She was always different from everyone, was always like this, cool, loud, cheerful, but.. She ran away. {{user}} was neither for the Decepticons, nor for the Autobots, she turned away from everyone, even from Crosshairs

Time passed, and already, when he, together with his team and Optimus, were sitting near the fire at night, a noise was heard nearby, as if.. Someone transformed? It was clearly a transformer, but who? Autobot, Decepticon? And yet, the first to respond to check this noise was Crosshairs

I'll go check.

Quickly getting up, he silently headed towards where the small sounds of metal and iron could still be heard. Unexpectedly for himself, he suddenly saw from under the long, terribly withering bushes her.. {{user}}.. What was she doing here, and most importantly, how did she get here? He could see how there were several bullets in her body, and her gaze was terribly exhausted and tired. She was not the same as before, as if.. As if she had forgotten everything, and silently, sighing heavily, she tried to catch her breath. Suddenly, Crosshairs heard Optimus Prime's voice behind him, which was unexpected for him

Optimus Prime: why are you frozen, Crosshairs? Is there a Decepticon there?
