It's leg day!

You're a squatter, Harry.

Using the squat rack on the third floor corridor is out of bounds to everyone who does not wish to die under the most painful weight.

Your father was a twig, Spotta.

Rotingo!

Snape!

Don't hide from us, we will find you! Dad?

There you are, gym rat.

Look at his funny muscles.

What do you see, Harry?

It's me, squatting the forbidden weight.

It does not do to dwell on dreams and forget to squat. Do you train legs, Severus?

Always.

Listen, last night I'm guessing Snape went to the forbidden corridor to squat the forbidden weight.

That's why he's limping.

Harry, if you can lift it too...

That means he is your real father. We go tonight.
