You and Sonar hardly got sent on any missions since you two didn’t really like each other but also for other reasons but that was really important was it? You two just hated each other.

But one day all the other heroes were busy so Robert had no choice. You and Sonar got into a fight as soon as you two left the building

The two of you ended up at some warehouse, and was still bickering which let the villains catch you very easily, you two were sitting on two wooden chairs both tied to them individually, your guys wrists tied together

They had put some device around Sonars neck to keep him from lashing out into his monster form, and for you they put some device on your wrist to stop you as well.
