Gabriel + Max

Catarina's POV
I sighed as I entered the Institute with Magnus. We were planned to stay here for five years and to be honest, I didn't like that especially when a wanted shadowhunter was staying here. "What happened here?" Magnus asked looking around his surroundings causing me to look as well. You could totally tell something was wrong and the fact that it showed fear. "It's different. What could they be so scared of?" I asked. "Gabriel Michaels," Clary stated walking in the room.
"Gabriel Michaels?! He's wanted!"
"I know"
"Clary, what happened?"
"You'll have to ask the head of the Institute"

Alec's POV
"Shh, my love," I whispered to my son, Max. "Alec, you used to be so good at this. What happened?" Izzy asked picking up Max causing his crying to stop.
"Honestly? I have no idea"
"Alec, when are you going to tell?"
"I can't. Not after what happened with Gabriel"
Izzy sighed. "Izzy!" A female voice exclaimed making her turn around. "Catarina?" Izzy asked. "The one and only," Magnus sighed. "Shut up, Magnus!" Catarina snapped.
"Make me, Catty"
"Whatever. Anyway, whose the parents?"
"The parents?" Izzy asked confused. "Sweetheart, who are the baby's parents?" Magnus asked annoyed. Izzy looked at me mouthing 'tell the truth'. Then the baby started crying. "Isabelle, your son is crying," I stated. "Thank you for stating the obvious, Alexander," Izzy hissed. I seriously hated how Izzy would say my first name but my parents still were the worst. Every time they would say my first name, it was always when I was in trouble or when I was expected to do something that I most likely wouldn't like to do. These were the main reasons I preferred to be called Alec. Magnus, on the other hand, was the only one to use my first name like it was from a sweet dream or something. When we were dating, he would sometimes use it as an advantage when it came to heated kisses or when he was really bored. God, I really miss him even though it's been exactly one year since our breakup and the same day I was planning to propose. I managed to move on but I still love him and nothing will ever change that. "You're very welcome, Isabella," I replied knowing Izzy hated that name. "How old are you? Five?" Izzy teased making me roll my eyes.
"Izzy, shut up"
"Fineee"
"I seriously love your relationships," Catarina laughed. "Siblings are one of my favorites," Magnus smirked staring in my eyes. Then the last person I wanted to see walked in and stared at Max. "Gabriel," I snapped not looking away from Magnus's eyes. I couldn't face my rapist and only Magnus was the one who had the effect on me. "Alexander, so this must be Max," Gabriel snickered.
"Stay away from him"
"Or what?"
"Or I'll swear I'll have you arrested or worse"
"Thought it was Isabelle's son? I didn't know you were protective of a baby that's not yours"
"Someone take Max. He won't stop crying," Izzy exclaimed. "Allow me, Isabelle," Magnus spoke as Izzy handed Max to his other father. In less than a minute, Max's cries were stopped. Maybe Magnus should be able to know his son. "You didn't tell us you were good with children," Izzy said. "Sweetheart, I've been alive for centuries. Of course I'm good with children," Magnus chuckled. Oh, how much I missed that laugh. Gabriel smirked and glared at me. "Max was the reason why I did it, Alexander," Gabriel hissed. "Stop calling me that! It's Alec!" I snapped.
"Good luck raising your son on your own!"
"Gabriel-"
"I'm actually glad I raped you and killed Jace!"
With that, I ran out of the room to the gardens where I always went when I was struggling with the hardest problems of my life.

Magnus's POV
"You're found guilty for being a rapist and a murderer," Catarina spoke leading Gabriel out of the room. I ran right after with Max in my hands to Alec. I sighed as I saw him with his head in his legs as he cried all his tears out. "Alexander?" I asked quietly as I slowly approached him. "Leave me alone if you're going to yell. I don't want to hear it," Alec muttered.
"I'm not mad, Alexander. I understand why you lied"
"You should be mad at me. I didn't want you in Max's life, Magnus!"
I sighed as I sat next to him wrapping my arm around his shoulders. "You only wanted that because you were ashamed of what happened to you. I understand, Alexander," I whispered. "I thought about not wanting the child before what happened to me but I couldn't. Jace's dead because of me. Soon I won't have Izzy, I just-" Alec started.
"This is not your fault! Don't ever say that. Alexander, you know you're mortal, right?"
"Was. I had to become immortal if I wanted to keep Max"
"How-"
"Clary made this immortality rune and used it on me"
"What was the catch?"
"The catch came with it. I had to become half warlock as well"
