@poisonivyrobin asks: Why did you and Jasper capture Lapis?

(This is actually my theory so if it's completely wrong I might go back later and write an "Edit:" for the correct reason)

You see, originally Lapis was assigned as my main source of information, since she had been on Earth for a long time. We didn't capture her. But she refused to give us all the information, so we put her in one of the cells, planning to let her out when she finally gave in.
