Just the small details
When Alec was holding his mother after she confessed that Robert had been cheating on her, Alec told Maryse she could come back with Max to live in the institute and Maryse said she couldn’t because of her duties but that she wished she could.
In the time she said this we had a close up of Alec where we saw him clenching his eyes shut (something we’ve seen him do when he’s trying to get ahold of his emotions) and it just made me think.
Was Alec trying to contain his anger at the clave and Robert? Or was he trying to keep himself from getting emotional?
How many times throughout his life has Alec probably asked this question of when his mom and dad would be coming back to New York for them? How many times has he been told they couldn’t because of the clave?
All I can see is a lonely kid wishing for his parents to be there for him while he not only dealt with raising Izzy and Jace and making sure they stayed safe and out of trouble,
But also the start to him questioning his sexuality
To be given all the responsibilities of an adult at such a young age because his parents were never around and therefore forced him to grow up too fast, pushing aside all of his own needs and emotions because that’s the only way he knew how to survive.
