Due to Marks fatal injuries from the devastating plane crash mark was in a coma that he may not have woken up from. Calli and all the others stayed by marks side for days on end waiting for him to come to. For weeks on end calli spends all her time by marks side praying and hoping he wakes up to see their child. How could Sophia grow up without a father? How could calli go on without her best friend? She takes on the rolls of cleaning him, and checking his stats. While also trying to cope with Arizona who had recently lost her leg in the same tragic plane crash as mark. Calli's whole world is falling apart around her. Who can she turn to for help? Shepard, noticing her completely exhaustion tells her to go home and he will take over for the night. Calli is obviously reluctant. She could never be able to bare him coding while she was at home asleep. Dreading that phone call that could ruin her whole life. As calli went home that night she cooked dinner for Sophia. She was so happy to have spent time with her child but couldn't help but miss Mark. Sophia was the spitting imagine of him, she had his eyes and definitely his alluring smile. At that point she knew if she lost mark she couldn't bare it. Having to see Sophia and having that constant image of Mark would kill her. Calli cleaned the kitchen and sobbed knowing that the chance of losing him is so high. Laying in her bed starring at the ceiling thinking about how he once laid there with her. Her eyes closed slowly and then all at once. Finally she was able to sleep in peace. Until she was awoke by a page from the hospital. Was Mark okay? Where was Shepard? Calli races to the hospital preparing for the worst. Running down the long halls it seemed like she would never make it to him. The doors open and he is awake! Crying from joy she hugs him tightly. Shepard being Marks doctor monitors him for a few days. His stats all magnificently rising better than ever. He often asks to see Sophia. Sophia loves her father and the pure joy Mark has when he sees her is like no other. Chief Richard notices Mark improving rapidly and cannot help but inform Shepard that it looks like "the surge". Shepard disagrees this couldn't be Marks last surge of energy before he crashes. He was doing so well and getting better every day. They both refused to tell Calli that it may be the surge that would devastate her. The chief and Mark start to write up his do not resuscitate papers without Calli's knowledge. Mark becomes very emotional, thinking about Sophia and leaving her fatherless. He thinks about calli and Shepard. All his friends and coworkers. Calli visits regularly and still helps clean and fix him up. Mark still has been doing better but he has a long road to recovery if he would like to practice again. Avery keeps him up to date on all the upcoming surgeries and tries to keep him motivated. Progress is shown and mark is allowed to leave the ICU. Calli could not be any happier. Her daughter will have a father! But now calli had to focus all her time on making sure Arizona was getting better. Her leg amputation was causing her to become depressed and very angry. There was a high risk of infection with such a big wound. Calli had barely noticed Arizona slowly slipping away. Since Mark was doing remarkably better she was able to stay with Arizona more often. Trying her hardest Calli was forever by Arizona's side hoping she would make the same recovery as Mark but Arizona was distant and mad at everyone. She pushed away all the friends who came to see her and eventually became angry with Calli for trying too hard. Arizona was miserable and wondering why this happened to her and not anyone else. She had a wonderful life until the plane crash and now she just wants to die. Noticing her lover depression Calli thinks she should pull Calli out of the hospital care and bring her home. Home where Calli, Mark, Arizona, and Sophia all live. Mark is discharged from hospital care after he finished his physical rehab and Shepard signs off on his release. Calli notices a significant change in Mark and Arizona's mood and wellness when Sophia is around. Both of them are on bed rest and cannot possibly watch a 2 year old by their selves so she hires a nanny for Sophia in hopes it will change their moods and aid in recovery. She is feeling the pressure of having to cook and clean around the house all while having to work at the hospital. Not to mention she is losing time with Sophia because of it.
