Are Kled and Teemo actually... related?
Kled says about Teemo:
Just 'cause we was kin don't mean I ain't feeding you to Skaarl! Hey cous', glad you came to visit! A relative's just another unwanted guest.
Now, I could see how he calls him "kin" and "cous" just because they are both Yordles, but word "relative" seems to mean they have actual blood ties, even if distant ones.
This would check out, as they are both wacko Yordle killers and such things sometimes run in the family, but I need a confirmation.
