Episode 4 question

A question in anticipation of Elf-Help episode 4 (just three more days!):

In episode 3, Coby (the dog-boy) says to Mar (the fat kid), "But I thought you already -- "

The sentence finishes:

a). " -- had sexual relations with a woman."
b). " -- served with a band of Amazon Kobold Marauders."
c). None of the above. (eg. Coby is interrupted, thus saving the strip from a rating higher than PG).
