(Sorry if The Doctor doesn't feel in character, I needed to say that)

Severus's POV

The Master/Snape was able to escape The Doctor and his crew of kids. "Don't think for one second I'm letting you kill any more people I care about," Snape hissed in his mind.

"We shall see about that." The Master chuckled as he finally got to the entrance of Gringotts. "So how do we get into this place?" The Master asked as he was scanning his surroundings.

Finally Severus complied with The Master as they got to the head Goblin. "I'd like to see volt 687 please." He gritted his teeth. The Master didn't know the Sorcerer's Stone was already taken and hidden somewhere else.

The Goblin eyed the tall man in front of him. Severus hoped that the sweat that was trickling down his forehead wasn't noticeable.

"Can I see the key please?" The Goblin asked as he was leaning over his desk. He sat back down as Severus handed the key over.

'Can you hurry this up please?' The Master said. He was making Severus's skin crawl. 'I'm doing the best I can, under the circumstance.' Severus said in his mind to The Master. Severus thought he was strong enough for Occlumency but The Master was too strong.

When the paperwork was finished, the Goblin stepped out of his desk, and walked towards the exit and paused to turn around. "Follow me, please." He said with a pointed look.

The Doctor's POV

Again, he was feeling helpless. He tried his power of suggestion, but he failed his former friend. Looking at the worried glances the kids had, he felt like he failed his students. His last stop was Hermione, who still had that angry look on her face.

She rolled her eyes. "Oh come on, do I have to spell it out for you?" She paused and took her wand out. "Use Occlumency."

"Occlu-what?" The Doctor asked then rubbed his forehead.

"Occlumency is used for memories. It can prevent a Legilimens from accessing one's thoughts and feelings, or influencing them." Hermione interjected.

"Honestly Goyal, you'd think they'd pick a smart teacher." Draco muttered towards his friend.

The Doctor glared at Draco.

"Not helping, Draco." Hermione grimaced and turned around to glare at him. She turned back to The Doctor. "It just means, that we can still try and take The Master out of Severus. Maybe it takes more than one person to do the spell, since The Master is has too strong of a hold on Professor Snape."

Meanwhile, Harry was still holding onto Professor Dumbledore who had fallen to his death by Professor Snape, who was in fact The Master. Finally, he turned around to face his classmates and then Hermione and The Doctor. "I'll go with you." He muttered and stood up from where Dumbledore's body lay.

"Now, now. Let's not be hasty. I just want to clarify, that this will not harm The Master." The Doctor said.

"Of course, it's safe." Hermione said.

The Doctor, Hermione, Ron and Harry decided to go to Gringotts in search for The Master.

Please bare with me! I'm almost done with this story!
