Narrative:

An A321 was on a 4 mile final for runway 36R. I put the other aircraft into position. When the A321 was on a 2 mile final I cleared the aircraft for taxi off. The A321 on very short final decided to go around on his own. I then told him to go around. Once I saw the A321 climbing I turned him to a 90 degree heading and told him to climb to 4;000 ft. A departure was still on the RNAV departure and was being caught by the A321. I issued a 130 heading to the A321 and told the departure to fly heading 360. Once the A321 was southeast bound I shipped him to the final controller and turned the departure to a 90 heading and shipped him to departure. It was a simple go around until they got in the clouds and I could not provide visual anymore.
