The two first met in the second season during their freshman year at Degrassi Community School. Ellie had developed a crush on Marco, and he asked her out, even though his feelings for her were only platonic. When Ellie wanted to take their relationship further, Marco's confused feelings about his sexuality cause him to come out to her. Ellie agrees to pretend to be his girlfriend until he was able to figure things out, though the charade quickly grew tiring for her. The two broke up, but remained best friends all the way until their last season on the show. After graduating high school, Marco and Ellie become roommates for their freshman year of college, but at the end of the year, they decided to move out on their own because they were too dependent on each other.
