'Thank you, minister' said Snape politely.

As the minister and her escort left, Snape turned to professor McGonagall.
'Pleased to see me, are you, Minerva? It's writen all over your face you know.'
She turned away and muttered under her breath.
'Very, Headmaster.'
'Oh! And, Minerva, my first doing as headmaster is to hire new teachers for DADA and Muggle studies, I believe the old teacher is not going to make it, pitty.'
'And who would those be?' she asked crisply.
'Amicus and Alectro Carrow.' said Snape.' Any problem with that, prof. McGonagall?'
'No, of course not' she replied curtly.

The atmosphere in the great hall was as cold as ice. Nobody spoak as Snape ascended to the staff table, followed by a sour looking McGonagall

Snape sat down in the headmaster's chair. Professor McGonagall took the seat next to him, trying forcefully to avoid the questioning gazes that were fixed on her.

'Hello! What a pleasure to see my old coleagues. I hope you are pleased to have me back, as Headmaster of Hoguarts.' said Snape mockingly. Some teachers looked at him with anger, some with disbelief, and others, like professor McGonagall, with disgust.

They started eating. Everyone was looking down at their own plate. Snape leaned closer to professor McGonagall, who was cutting her steak with all the concentretion she could muster, and whispered.
'How do I look in Dumbledore's chair? Now I'll have my own portret next to the other headmasters. Don't you think I'll look great between Phineas Nigellus and your dear Dumbledore?
'Don't worry, I'll make sure you get there as fast as possible,Severus.' said professor McGonagall through greeted teath, just loud enough that he could hear.
