Sana Bakkoush put a chest of drawers against her door before she let herself cry.
Before she allowed herself a moment of vulnerability she had to make sure that no one was able to see her.
She has reached out so much to people and loved them through their pain but she just can’t burden someone with her own. So she locks herself in her room, probably scolding herself as she feels the tears coming as her throat aches with the strength of a sob. But she doesn’t allow herself this she only lets a just a few tears fall and then composes herself.
Sana Bakkoush is probably the strongest person in this show and that very quality is also her weakness.
