The bed is too big without you

Alec is the only omega left and is pregnant. But Alec has been keeping this secret from Magnus as he has only had miscarriages and he wants to spare Magnus the pain of going through another miscarriage. But when Magnus is sent home from the war against Valentine because he almost died from his injuries, Alec can't keep it a secret anymore. But how will Magnus react?

Valentine wants Alec desperately because he is the last omega and that is the reason he started the war. Valentine won't end the war until he has Alec. Magnus wants to fight Valentine to protect Alec, but by doing this he has been unintentionally neglecting Alec and their adopted daughter Madzie. Alec tries to persuade Magnus to stay but Magnus won't rest until Valentine has been defeated and Alec is safe from him.
