He thinks love is over for him. He doesn’t believe there’s a possibility, so she shows him the way. -Brendan Coyle (x)
Her story line was indeed already on that path but it was actually given to Matt to write. And she got alot more screen time, even in the background there were alot more shots of her and music numbers. Now with Mark, he was really famous in the start because of his badboy character, her linked to him expanded her brand, just because she was linked to him. Im not saying matt actually gave santana anything big, but asisde from her storyline she got alot more screentime.
