Carl was introduced in December of 1983 as Felicia's
secret lover from abroad. They
had met in Paris. Their affair, as
depicted on the show, was
short-lived. Neither had any real
affection for the other. At the
time, Carl was too obsessed with gaining revenge on Mac Cory
to devote his affections to Felicia.
Later on both became friends due to their closeness to Rachel.
