‘Grey’s Anatomy’ Episode 21, Spoilers and News Update: A War in the Offing between Callie and Arizona

Episode 20 of "Grey's Anatomy" gave us a good lesson on gun culture and also brought up the issues between Alex and Jo as the latter was keeping a gun in their flat without his knowledge.

Well, the next episode (Episode 21) will also focus on the tussle is between Callie and Arizona, who appeared to be on the healing path, but now are going to get embroiled in a major fight.

According to reports, Callie wants to move to New York along with Sophia to settle with Penny but Arizona does not want to be separated from their daughter. Previously, she had encouraged Callie about her plan to move with Penny but she had no idea that it also involved Sophia.

Arizona is very close to Sophia and therefore, when she gets to know of the entire plan, she will be furious and think of waging a custody battle. However, Callie has not finalized everything and is still planning. She broached the topic with Arizona just to know her point of view.

But the very mention of the enrollment application in a New York school sends Arizona in a tizzy and she is furious. She tells Callie that she will have to deal with her lawyer now and therefore, it seems a custody battle is imminent.

Titled "You're Gonna Need Someone on Your Side", the episode will also see the duo rallying support for themselves from the doctors of Grey Sloan. In the trailer, Alex is seen saying if he is being asked to take a stand and then immediately Callie comes onto the scene. But it is more likely that he is talking to Arizona as both are in the same department.

Arizona is also seen trying to get April and Jackson on her side as the former gets an ultrasound in her presence. Callie goes to Meredith and requests her if she can ask a question. With the tagline of the promo announcing "The line has been drawn, Choose your side," it is really about taking sides in a fight.
