The school forgot about you and Snape when Digory had died. The whole school was distraught and it was made worse by finding Moody was actually Barty Crouch Jr.

Voldemort had returned. Which meant Severus was always more watchful and went away for periods of time. He sometimes told you to leave the house, if Belitrix came knocking.

He was much more relieved, that the new term started, as it allowed you and him to be safe enough under Dumbledore's protection.

Oh, how wrong you and he was, as your premonition was going to become a reality.

You decide to join the order of the phoenix, working, just in case Severus is thrown out of the order you could feed information to keep his place as a spy and is there when Harry arrives at Grimmauld Place and stay while Severus goes off and says he would meet you at Hogwarts.

You get to know all the members of the order of the phoenix and they all seem to like and trust you, as Dumbledore and Harry vouched for you. You would feedback information to Severus, making it seem to the death eaters that he was still apart of the order.
