A/N: The surprise is in this chapter.

Lillian and Harry walked into the room where a troll was lying on the ground knocked out.

"We've had devil snare which is Sprout's. Flitwick must have charm the keys. McGonagall transform the chessman to make them alive. The troll must have been Quirrell and that leaves…" began Lillian.

"Your father test," said Harry.

"Yeah."

"Well at least we have you."

"What do you mean?"

"If anyone can figure it out it would be you. After all you are his daughter."

"I guess."

"Come on let's do this."

They walked into the other room and saw a table with a bunch of different bottles on it.

"So what do we have to do?" asked Harry looking around?

"Look," said Lillian as she pick up a roll of paper. "It's indeed my father's handwriting. It saids:"

Danger lies before you, while safety lies behind,

Two of us will help you, whichever you find,

One among us seven will let you move ahead,

Another will transport the drinker back instead,

Two among our number hold only nettle wine,

Three of us are killers, waiting hidden in a line.

Choose, unless you wish to stay here forevermore,

To help you in your choice, we give you these clues four:

First, however slyly the poison tries to hide

You will always find some on nettle wine's left side;

Second, different are those who stand at either end,

But if you would move onwards, neither is your friend;

Third, as you see clearly, all are different sizes;

Neither dwarf nor giant holds death in their insides;

Fourth, the second left and the second right

Are twins once you taste them, though different at first sight.

Lillian let out a sigh and Harry was confused but he saw her simile and was now more confused the ever.

"This is brilliant. My dad is a genius," said Lillian.

"What are you talking about?" asked Harry.

"This isn't magic. It's logic!" said Lillian who was very excited. "A puzzle. A lot of great wizards haven't got one once of logic and they would be suck in here for ever."
"But so will we, won't we?"

"Of course not. Everything we need to know is right here on this paper. Seven bottles: three are poison, two are wine; one will get us safely through the black fire and one will get us back though the purple."

"But how are we suppose to know which one to drink?"

"Give me a minute."

So Harry waited as Lillian read it over again. She glanced at the bottles and clapped her hands after a short while.

"Got it. The small bottle will get us though the black fire, towards the stone," said Lillian.

"There's only enough there for one of us. That's hardly one swallow. Which one gets us back thought the purple flames?"

Lillian pointed to the round bottle and then picks it up while Harry picked up the black one.

"You drink that one and listen go help Hermonie get Ron out of here but using the brooms and that will get you out past Fluffy and don't forget the cloaks. Then go to the owlery and send a note to Dumbledore. We will need him. I might be able to hold whoever it is for a while but I'm no match for whoever it is alone."

"But Harry there might be Voldermort down there!"

"I got lucky once didn't I? You have to do this Lillian."

"Harry…."

With that Lillian walked over to him and lightly kiss him on the cheek.

"You better come back to me," said Lillian.

"I will. Now go."

Lillian nodded and drank the potion and quickly left the room with tears of worry in her eyes.

A/N: I am not writing the fight with Harry and Voldermort due to the fact that the next chapter is them escaping and going to the owlery. Oh Snape in the next chapter.
