background info : kelv was walking out of studio when suddenly he hopped back and kept going "pins and needles" (obviously his leg went numb), so we were mocking him about being old.

Shah mentioned about the cockroach which was found in kelv's food earlier on. That was why he said maybe when kelv returned from his exchange in year 4 term 1, he'll find the 2nd generation of the cockroach in his food again. haha
