foreshadowing, or just a lil jokey joke?

in s1:e2, Chase cracks a joke to Foreman saying that to get a paternity test on a patient for a bet with House; they should say he has Huntington's Disease and his whole family needs to be tested "or else they'll all die," and Foreman gets a good laugh out of it. Wild(e) to think he later dates someone with Huntington's.
