I’ll tell you something. Alec has always been the protector, the one who make sure that everyone else is fine. Alec is worrying all the time about a lot of people, specially being a big brother and one of the best shadowhunters out there. You can say Alec is pretty much used to be the one protecting others by now. When everybody is going crazy, he’s the one who stops to think, who remains calm.
And then, what did we see in Shadowhunters 2x10, in that second hug after Alec’s and Magnus’ love confession?
Alec was just there, hugging Magnus tightly, not wanting to let go. Not thinking about anything or anyone else, not caring about who was watching or around them, not caring about anything in the world but Magnus. Alec was just there, doing what he wanted to do, because he wanted to do it. Because he needed to do it —to feel Magnus there, safe and alive, close to him.
And Magnus? Magnus was hugging Alec just as tightly. Running soothing circles with his thumb in Alec’s shoulder, trying to calm him, to assure him that yes, he’s there, he’s okay and he’s not going anywhere. Trying to ease Alec’s pain, even when Magnus was just as desperate.
In that hug, in Magnus’ embrace, Alec was not the protector. Alec was just himself, letting everything go in Magnus’ arms, being his real self —the self who loves Magnus, deeply and desesperately. And Magnus was there to calm Alec, to protect him —protect him from his darkest thoughts, from his fears.
Alec and Magnus just complement each other so well. They’re just so good for each other.
