This was a simple scene description that I came up that would best show Deadpool without him being a part of the main story. Was also written for non other then Ryan Reynolds.

[A handcuffed Logan exits an elevator with several armed guards]
[They walk down a hallway with bared doors on each side]
[At the end of the hallway is an overweight guard and a skinny guard with glasses guarding a cell]
Voice From Inside Cell - I’m going to kill you all….[Laughs] When I get out of here Im going to kill each of you!
[Arms come out of the bars with red gloves…points at the overweight guard]
Deadpool – Especially you fats…..I just don’t like how massive you are. Ever hear of Nutri-system? But Goggles your chill.
[Over weight guard looks annoyed]
[Camera zooms to just the small barbed cell with Deadpools Arms]
[Deadpool breaks the 4th wall and talks to the audience]
Deadpool – Whelp there’s your cameo. Let’s hope they don’t screw me up in this time...
[His hands make double thumbs up sign]
[Logan and guards pass Deadpools cell]
Deadpool – Aye! Logan buddy its me Deadpool!
Logan – Do you ever shut up Wilson?
[Deadpool sticks up his right middle finger]
Deadpool – You know I still hate you. Soooo uhmm….Suck It Wolverine!
[Logan and guards exit threw a door at the other end of the hallway]
