Is Andrew McCarthy Leaving "The Resident"?
An American actor, Andrew McCarthy, got introduced in the last episode of the series. Also, looking at the end, the actor doesn't seem to be taking his leave now.
Moreover, the show seems to have more things for the actor and his character, with more twists and turns. He has portrayed the character of Dr. Ian Sullivan, the father of Dr. Kincaid "Cade" Sullivan.
In the last episode of the series, the actor made his appearance to donate his blood to her. However, he seems to have a complicated bonding with his family.
What else? Dr. Ian seems to be in the town for more than saving his daughter. Taking that into account, the actor might not be taking his leave soon if the series got renewed for its sixth season.
