“Give it here!” I allowed him to wrest it from my grasp. In any case I could not have prevented him. He shoved me backwards against the rusty bulkhead with a clang. He pushed the nozzle of the syringe down into the retort and withdrew it filled with Moon Glow. He opened an inspection plate in his ventral region and squirted himself generously. It was quite a dose.
