No, Snape is not dead!

Sarah breathed deeply. She would have to be civil with Jane.
'Congratulations.' she said to Jane after the feast.
Jane smirked.
'Watch out. Sooner or later, I will have your power and position.' she hissed.
'You don't scare me anymore.' Sarah said.
'You're only 22. I'm much older, much more clever, and much more powerful.'
She walked off. Sarah felt ready to curse her.
'I highly doubt she is.' said a low voice.
Snape rested a hand on Sarah's shoulder.
'I'm... actually scared of her Sev. I still have memories about last time she invaded my life.' Sarah admitted.
Snape gently squeezed her shoulder.
'Hey, you'll be fine. I won't let her hurt you.' he said softly.
'We've come a long way. Remember the first time we met?' she asked.
'Vaguely. Wasn't I pulling you up Diagon Alley by your school bag?' he said.
'Something like that.' said Sarah.
She went to her office, and sat at her desk. She dipped a quill in her ink pot, and began to write a letter to Sirius

Hey Dad,

I'm in a bit of a dilema. Remember Jane? Y'know, that hag that tried to kill me? Yeah, she's our new astronomy teacher.

I'm not entirely sure what to do. I'm, still scared of her. And she's already threatened me, saying she'll soon have my position.

I'm really unsure as to what to do. Help?

Sarah

She rolled it up, sealed it, and attached it to Binky's leg.
'Dad, okay?' she whispered.
The owl nibbled her finger, and took off.

Sirius's reply was short and sweet.

Sarah,

Be in your room, tomorrow at 1 'o' clock.

Dad
