Well guys this was before Snart died
FWI Leonard Snart is one of my favorite characters of all times ^^ ❤️

As for Oblivion and Raven, they went separate ways not knowing they had the same destination. Those two were not easy to track, besides it was night time. Raven and Oblivion looked confused to see each other arriving to the same hotel, same room. Raven whispered
- What the hell are you doing here?
- I came to get shadow, what are YOU doing here?
- Came to bring, John. Wait a second...
the demon and Oblivion pressed their ears against the door. Both of them heard noises that came from inside the hotel room.
- ungh Aaah aah, mmmmh mmmhmmh oh yeah baby oh yeah! aah, oh oh oh, ahhh ahhh!
Both of them quickly got far away from the door. It was quite odd to see a demon so spooked. His bright purple eyes were wide open.
- Maybe... we should come back in the morning...
- Strongly agree!
Oblivion and Raven left to their separate ways to find a place where they would stay at for the night. They had to get up very early in the morning because the hitman and his lover moved quickly from place to place. Oblivion made sure to get Shadow as quick as possible and Raven went to have a word with John. The awkward demon began to speak making it obvious he did not want to be there.
- Look, I don't like you and I know you don't like me. So let's make this quick can we? Omega, my best bud, found a way to go back home... to Fortnite.
John kept it quiet. He thought about it for a few seconds then he turned around and started to walk away as he said.
- No, thank you
- Excuse me what? I, I thought you wanted to go back
- Well... you thought wrong. I am doing just fine here
- How? Being someone who in Fortnite the citizens would hate and fear? Look, you have to come back. I did NOT come all the way here and hear you have sex just for you to say "no, thank you"
- I have nothing else to talk to you about demon. Now, leave
- Or what?
John pulled out his gun and pointed at him saying
- Or I'll make you
Raven did not look amused. He looked the man straight in the eyes as he said
- Oh... I see, there is a reason why you don't want to come back. You don't want to remember what happened with your son right?
- This has nothing to do with his betrayal
Raven placed his hand on John's shoulder bringing him closer. The man in the suit looked at him annoyed and not comfortable at all.
- Look, I hate to break it to you, Honey. But your son didn't betray you!
John moved the demons hand away from him as he asked in confusion.
- what are you talking about?
- Well... Johnny, I, let's say, I demonized him.
- You did WHAT?
- Wait! We are all friends here remember? I can get you back to your son, Johnny.
- Fine. But I am going to make sure I send you back to the Underworld after we are back. You better give me my boy back.
- Okay, Okay geez, somebody didn't have his coffee this morning... kidding

John's POV
The guilt consumes me... my son. I'll be coming home in the first light of dawn, my steady gait making my way down the street. I will be coming home under lantern-shine as its golden rays mingle with the first light of a new day. I'll be coming home to your love and so that you can feel mine wrapping around you as a comforting blanket. So sleep well, my angel, and when you awake you will find me home, as if I never left.
End of John's POV

Finally the whole group met up. They were near STAR labs because that's where team flash always is.
- So the name is... Barry Allen?
- correct raven. Now we have to make sure we have something that is freezing. Oblivion got any ideas?
- Well... according to this, there's something with a... cold gun. Name is Leonard Snart/Capitan Cold world-class thief.
- Leonard Snart... how do we find him?
- I have an idea.
John was quiet on the back. He was desperate to go back to his son he step to the front as he said.
- I know to find him. After all that's my job.
Once again they had to change their location. This time they found themselves at a bar in Central City. It was nearly empty except that two gentlemen were at a table drinking.
John told them to wait there and he approached to the two men. Heat wave quickly reacted by pointing his heat gun at the man in the suit. As for Leonard he merely had reaction. He was a calm man who knew how to handle a situation.
- Easy, Mick. We don't want to spook our guest now do we?
John sat in front of Leonard making eye contact.
- I need a favor from you Mr. Snart
- mm what kind of favor? Any fancy diamond that needs to be freed from captivity?
- Im afraid we don't need your thief skills in this job.
- Then what can possibly want from me Mr...
- Oh right where are my manners... Name's John Wick

Mick couldn't avoid laughing as he said
- Well, your dad got you wicked good
John rolled his eyes and turned back to Leonard.
- I need your cold gun.
Leonard instantly grabbed his cold gun giving it a gentle hug as he asked with concern
- My cold gun? It doesn't separate from me. At. Any. Given. Time.
- Then I need you to come with me Mr. Snart we need to catch the flash.
- Hmm the scarlet speedster.That's not for anyone to kill. If anyone can hurt him it would be me.
- We don't mean any harm we just need to get to his Vibe friend and then we can go back to our dimension. What? Well I know it sounds crazy and I don't expect for you to believe us but-
- Oh I do. Otherwise those freaks wouldn't be standing there at the corner. Those are faces you don't see everywhere. Besides, i have time traveled myself so chances are limitless. Alright I'll help. With one condition. If anyone touches that speedster I can ice the hell out of each and every single one of you.
- understood, Mr. Snart. Now, shall we get going?
- Indeed...
