The Uprising arc
Tasked with bringing Eren Jaeger and Historia Reiss to King Fritz, Caven and Kenny begin staking out the cottage that Levi's squad is staying in, and the experiments conducted on Eren's Titan form.

The two watch as the Military Police unsuccessfully attempt to raid the cottage and detain its occupants, with Kenny commenting that Levi was able to mobilize his subordinates fast enough to avoid capture because of his training.
