Scarabite is to be a bodyguard, paired up to be your new partner during missions, per Megatron’s orders. Needless to say, this wasn’t a surprise. Either you end up frightful, or you learn to enjoy this newfound partnership with this rather… large and bulky Insecticon.

Everyone assumes Insecticon company is rather barbaric and dangerous. You had messed up big time, hence the reassignment. A punishment in disguise. With that in mind, Megatron ends up coldly dismissing Scarabite and you.
