Hot Wheels Battle Force 5/Heartwarming

"Zug: Zug like Stanford..."
 * Near the end of "My Man, Zug", Zemerik is ordering Zug to destroy Stanford, who is at Zug's mercy. However, Zug decides to spare Stanford after shutting off the surveillance camera that allowed Zemerik to observe what was going on. Why did he do this?:

"Zemerik: Zug, what happened!?
 * What comes next, unfortunately, is just tragic. After helping Stanford get back in the Reverb, Zug reactivates the surveillance camera:

Zug: He... got away, Lord Zemerik.

Zemerik: Rrgh! Return to base!! For reprogramming!"


 * Zug gets yet another one (noticing a pattern?) in Get Zemerik when they're in the badlands and Zug gets badly damaged. Zemerik wonders why he stopped and discovers that Zug's power is almost drained, who proceeds to give Zemerik his own power core in order to keep his master alive.
 * Adding to the moment is Zemerik praising his loyalty, calling him a friend, and promising to come back for him.
