In King Lear, why did Lear decide to take Caius into his service?
"Caius," as he calls himself, first appears in Act I scene 4. Caius is actually the disguised Duke of Kent who, having been banished in Act I scene 1 after telling the truth to his king now disguises himself in order to continue to serve his liege now. Ironically, it is clear right from the very beginning that Caius actually does precisely what Kent did: tell the truth to Lear. However, his disguise and identity as "fool" seems to make the truth and his honesty much more palatable to Lear than his previous honesty when he was speaking as Duke of Kent. Note how Caius responds to Lear's question about what service he can offer:
I can keep honest counsel, ride, run, mar a curious tale in telling it, and deliver a plain message bluntly. That which ordinary men are fit for, I am qualified in. And the best of me is diligence.
