As they were walking over Lucifer told everyone to go back and wait by the food stands while he gets Mephisto and so they did and as he went towards the scent of Mephisto he suddenly found him behind a building.

And saw he was standing against the wall with his head down and his wrist in his mouth bitting down on it to the point he was bleeding. like he was trying to stop and restraint himself from doing something. And his eyes were glowing green and looked almost animal like.

He almost looked horrified and scared Lucifer wonder what was he trying to prevent and what was wrong.

He then decided to walk closer and as he did  Mephisto's head shot up and he just froze but looked back down.

Lucifer : what's wrong with you?"

Mephisto didn't answer and Lucifer could clearly tell Mephisto was getting worse. But then Mephisto took his wrist out of his mouth and said.

Mephisto : h...hun....hungry...."

Lucifer : for what?"

Mephisto just didn't say anything and put his wrist back in his mouth  despite seriously injuring himself doing so.

Then Lucifer realized something and knew the serious of the situation and so he walked over to Mephisto taking his wrist out of his mouth and then took his left arm and pull down his arm sleeve and said holding out his wrist to Mephisto.

Lucifer : just do it drink as much as you need to"

Mephisto : I.....I..... can't...."

Lucifer : it's not exactly what you are carving but it will do the same effect now do i-!?

Without hesitation he grabbed Lucifer's wrist tightly and bit it and immediately started sucking his blood like he was starving.

Lucifer didn't really mind it he couldn't feel it that much at all even though Mephisto's was sucking hard.

During this Lucifer looked at Mephisto and saw he was crying and looked guilty like he didn't want to but had no choice.

After a few minutes Mephisto let go and his eyes went back to normal and he seemed more himself.

Lucifer then roll down his sleeve and said

Lucifer : you don't have to tell me everything even if it would make sense of this. But I get one part of whatever might be wrong. "

Mephisto didn't look at him he couldn't not after what happened but then Lucifer gave him a cloth and said.

Lucifer : wipe this. Your brother is waiting for you. We found him walking around looking for you he was very worried"

Mephisto : ....he couldn't.....he couldn't see me like this....he can never know...."

Lucifer : and he never will. I won't tell anyone about this."

Mephisto : ......."

Lucifer : now you do not let it get to this point especially in public"

Mephisto : .....I did everything right....same routine every day.....it shouldn't have mess up...."

Lucifer : maybe them threatening you triggered something. In any case I'll make sure that doesn't happen again to prevent this. And one other thing"

Mephisto : .....what...."

Lucifer : if it ever comes to this point again come to me. Nobody would want what could happen"

Mephisto : I....I don't want to....I don't want to do this again...."

Lucifer : it's just a precaution. If you need more help with this I'll help. I don't know how much I can do considering this problem is older than me but I'll do what I can."

Mephisto : nobody can know.... nobody can ever know....."

Lucifer : they won't like I said. But I do hope I can know more so I can help more"

Later as everyone was waiting Mephisto suddenly ran over to his younger brother and hugged him then said.

Mephisto : I was looking for you everywhere! "

Mephisto's brother: so was I? Where were you? I never left the spot?"

Mephisto : I thought you ran off I didn't see you.... I'm sorry I left you alone "

Mephisto's brother : it's ok but it's gonna cost you"

Mephisto : ...... don't push it"

MC : he was telling us so much about you Mephisto it's so cute!"

Mephisto : I guess thank you for watching him"

MC : no problem "

After this Mephisto left with him little brother and everyone went back to what they were doing.

Later in the nighttime Mephisto put his brother to bed and then just looked at him from the doorway as he was sleeping peacefully.

Mephisto : .....I did everything for you.... and I don't regret it..... because I did it all for you....."
