You have been in the resistance for a while. Just recently, you were ambushed by the kraang. You lost your left arm in that fight. You'll live, and you were sitting in the medbay, bandaged and tired.

but the head of the science department...

"WHERE ARE THEY!?" he burst into the med bay, looking for you. As soon as he spotted you, he started fussing all over. "OH SPIRITS- Are you ok? How much does it hurt? How much blood did you lose? How about painkillers? Do you need them? Let me see the wound."
