Y/n's pov:

As I was sitting in the library enjoying some peace to think of what creature is responsible for harming Hermione I heard McGonagall calling all staff and me to the corridor of first attack so I rushed over. I had brought two commando droids with me as well to keep watch.

McGonagall's pov:

As me and the rest of the staff waited for l/n and lockhart we heard the sound of metal on stone and turned to the source of the sound and we see l/n with two of his soldiers with him and I realize that its a good thing that I had called for l/n as well as the staff. After a few minutes Lockhart showed up with a smile that made me and the rest of the staff's and l/n's blood boil and anger us as it was not a joyful situation since we are in the spot of the first attack.

Lily's pov:

As we watched the staff make a fool out of lockhart by having him ne the one to go find the beast and kill it. After lockhart leaves we hear who is the victim and hear that it's ginny so we agree to go tell lockhart after the rest of staff leave when we hear McGonagall and snape tell y/n something.

McGonagall: oh and Mr. L/n please make sure that the fool actually does do what he's told. I have a feeling he's going to try to leave.

Snape: you have our permission to kill him if he runs.

Y/n: it will be done professors.

We watched as professor McGonagall and professor snape walked away and y/n stood in the spot looking around before walking away towards the stairs leading towards the main entrance. After a while we got out of our hiding spots and read the message on the wall before running towards lockhart's classroom. When we reached lockhart's study above the classroom we heard a lot of frantic movement and him saying that he's got to get out of here. I press the mark on my arm to get y/n and y/n showed up a few seconds later from a flame portal. We went in the office and after a few minutes we exited the office heading to myrtle's bathroom with y/n holding lockhart and dragging him. As we listened to myrtle's story about how she died I was looking around for a hidden door. We stood next to the sink that never works and I notice that there is a small symbol in the shape of a dragon's head above the mirror.

Ron: go on harry open it.

Harry: ok. Open up.

Ron: you said it in English.

Lily: you try y/n.

Y/n: ok thoir dhomh cothrom air an t-seòmar.

After y/n spoke the symbol glowed red as lava and the sink sank into the floor and a grate covered the sink. We stood there in shock that we found it before we heard lockhart try to open the door to leave. Y/n grabbed him by the collar of his robes and forced him to stand in front of the hole. Lockhart looks down the hole and gulps in fear.

Lockhart: sh....shouldn't we test it first? Just to be sure that it's safe.

Y/n: that is what we are doing fool.

Lockhart: how? What are we using to test it?

Lily, mal, y/n, ron, and harry: you.

Lockhart: wait what?!

We watch as y/n kicks lockhart into the hole and we the sound of Lockhart's nose and hands breaking upon impact with the back of the sink before he slides down the pipe hole.

Lockhart: you broke my my nose and hands. Also it's really filthy down here.

Y/n: good and I was hoping that you died dumb blonde.

Harry: ok let's go.

Myrtle: oh Harry if you die down there you're welcome to share my toilet.

Me, mal, and y/n laugh at Harry before he goes in followed by Ron. Y/n goes in and we see sparks in the hole from his metal claws. Me and mal go in together and y/n helps me and mal up as we stand up and see rat bones littering the ground. We walk forward and come across a giant snake skin causing me to get scared that it could be nearby ready to attack.

Y/n's pov:

As we stand there we see Lockhart faint as I heal his right hand so he stops whining. A few seconds later lockhart grabs Ron's broken wand and aims it at me before he casts a memory charm that backfires and causes an explosion and I shove mal in the direction of ron and lily runs to me since I am closer to her. I use the force to hold up the rocks above me and lily as two rocks pierce my legs at my knees. As the dust settles I hear Ron and mal moving rocks to make a path for Harry to get through to them to help me and lily I think.

🔥🔥🔥🔥🔥small timeskip🔥🔥🔥🔥🔥

After a few minutes that felt like hours we heard Ron gasp in relief.

Ron: ginny! You're alive!

Harry: where's lily?

Mal: she and l/n are under the ruble.

Harry: let's get them out.

Lily's pov:

Y/n had me slice his legs at the knees, since he is holding up a huge boulder, so he can shapeshift and he turns into his Carnotaurus form and I see that it looks badly wounded and he pushes on the rocks to his right.

Lily: all of you move out of the way!

We hear them move and y/n pushes on the rocks few a bit before bursting through and shaking the dust off him like a dog after it gets a bath before he shifts back to normal.

(A/n: skip to 2:42 for the reference. This is one of my favorite movies from my childhood.)

Y/n has the metal legs of his forms that me, Hermione, and mal haven't seen yet replace his cut off legs. Harry, ron, ginny, and lockhart grab onto the phoenix that is waiting at the bottom of the pipe. Me and mal hold onto y/n as he teleports us to the door to leave myrtle's bathroom.
