So from what I heard, Wade wanted a family with Vanessa right? A baby?? A family of his own??
He would definitely treat Mary Puppins as his own actual biological daughter even though she's a deadpool, but she's the closest thing he has to an actual baby
And and Wade was no doubt happy for Laura that she has a Logan, not hers, but a Logan that she'll love and cherish all the same as her father
And Logan slowly opening himself to her and taking the parental role and treating her like she was always his own daughter
But oh my God IMAGINE PLEASE IMAGINE how HAPPY he would be when Laura refers to him as papa one day
Wade would always hang out and treat Laura like the questionable Uncle, and leaving the "father-bonding-and-other-fatherly-things" to Logan
But then one night, after she comes over for dinner and hangs out with them and now she has to return back to the X-Mansion she goes:
"Thanks for letting me come over agajn guys. Goodnight, love you Dad, love you Papi." And shuts the door and Wade almost trips over Mary Puppins.
"That's a little odd, baby peanut mentioned you twice. Must be really tired after tonight."
"Papi is you, bub."
He slowly turns to Logan, refusing to believe it
Before quietly and brokenly asking with so much joy
"I'm a dad?"
And if he cried that night, then that'll just be between him, Logan and Mary Puppins until Wade starts telling anyone and everyone that he's a step father and proceeds to prove how much of a great step father he can be
