Mephisto manage to find a path to the bottom of the cliff And saw just water it was a river and unconscious washed up next to it was Mammon.

Mephisto then quickly ran off to him and fell to his knees checking if he was alright but nothing. No pulse no heartbeat beat no breathing. Mephisto then attempted to try to do CPR anything to help Mammon but nothing was working.

He then just sat there hopeless not knowing what to do. All he could think about was how this was all his fault. That if he didn't play this prank on Mammon he would still be Alive.

Mammon risked his life for him died for him w hen he didn't deserve it.  Mephisto felt so bad and horrible. He felt this pain in his chest he never felt before and looked down and started crying and started getting angry at himself and yelled begging for Mammon to just wake up.

Mephisto  : DAMN IT MAMMON I'M SORRY! I'M SORRY OKAY! YOU CAN'T DIE! YOU HAVE TO WAKE UP! THIS WASN'T SUPPOSE
TO HAPPEN!!"

Mephisto was feeling immense guilt and pain for everything he did.

Mephisto : WHY DID YOU HAVE TO LOVE ME! YOU WOULD OF BEEN FINE IF YOU DIDN'T! IT WAS NEVER SUPPOSE TO GO THIS GO! WHY DID YOU HAVE TO BE SO NICE AND SELFLESS!"

Mephisto kept crying he couldn't help it or stop it this pain was just unbearable.

Mephisto : .....I ....I actually loved you....damn it....I actually felt for you....but it's too late....."

All Mephisto started thinking about now was all the things Mammon did for him even when he didn't treat him good Mammon always treated him like he was the most important thing to me which he has said.

Mammon was great and he took advantage of that he felt like he was the one who killed Mammon.

And eventually stop crying and just sat there doing nothing thinking this was it.

Suddenly Mephisto heard a gasp of breath and looked up and saw Mammon gasping for air and quickly sitting up spitting out water.

Mammon : gross! Man i-!?

Mephisto : .....heh....your an idiot.... even death doesn't want you...."

Mammon : I.... what are y-!?

Mephisto : I'm glad...... Because I do....."

Mephisto suddenly past out and Mammon quickly tried waking him up but nothing.

Mammon : Mephisto!? Mephisto!"

He then looked at his neck and saw it was bleeding a lot and turning black and that's when everyone showed up.

Mammon : Lucifer! Something is wrong with him!"

Lucifer looked at his neck and said looking worried.

Lucifer : it looks like he was posion curse with whatever he was cut with. We'll get him to Diavolo I Don't think I can fix this"

Later at the castle Mephisto was  in a room
With everyone with Diavolo and Barbatos
Trying to help him but nothing was working the wound stop bleeding but he wasn't waking up and his neck kept turning black and wasn't going away.

Barbatos : I am sorry there's seems to be nothing we can do"

Diavolo : this must be a powerful Curse"

Mephisto's Brother : he.... he's not going to die is he?"

Barbatos : we will try are best to not let that happen"

Mammon : ......this is my fault....."

Lucifer : what were both doing down there?"

Mammon : I was fighting the witch ....then we ended up at the cliff And she pushed me off and ran off. I held onto something and he showed up...he tried to pull me up but he was just pulling himself down....so I made him let go....next thing I know I woke up there....I for sure thought I died....pretty sure he thought I did.....I shouldn't have left him...."

Lucifer : it will be alright....."

Mammon : ....... I'm sorry....."

Mammon then walked over away and Lucifer then went after him.

Later in Mammon's room he was sitting on the couch looking at the sunglasses Mephisto's bought him. He felt horrible about everything.

Lucifer then sat down next to him and said.

Lucifer : ..... you care a  lot about him Don't you?"

Mammon :.....I do.... and I'll never forgive myself if he does Because of me...."

Lucifer : .....I'm sure he'll be fine. It just might take Time..."

Mammon : .....I should of stayed with him but instead I ran after the witch...."

Lucifer : believe me she will be delt with. But anyway no use dwelling on should of's."

Mammon : I know you hate him....but he's really not bad at all....."

Lucifer : he makes you happy. And I'll respect that. Guess I have to be polite since he is facing death"

Mammon :.....your so good at comforting people....."

Lucifer : give it time. I'm sure there is a way to stop The curse. Finding her may be are only solution."

Mammon : ....can you help me with something Lucifer?"

Lucifer : anything"

Mammon : the kid I saved....I Don't think she's safe with the witches. What if she tries to hurt her Because of me to?"

Lucifer : I'll retrieve her personality. I have a few word for the witches anyway"

Mammon : ....not in front of the kid"

Lucifer : Don't worry about it"

Mammon :......."
