Here's an alternate interpretation of "The Courtship of Wyatt's Father"

So Phoebe suggested that they just tell Piper and Leo about Chris: Phoebe: Hey, look, I have an idea. Call me crazy, but why don't we just tell them the truth. Here's what might have happened if they actually did tell them.

"Okay Paige, we have tried almost everything, what other choice do we have?" Phoebe was getting frustrated. She didn't want to upset Piper and Leo but she didn't want Chris to not exist in the future. "Well… what do you suggest?" Paige sighed, finally giving in. "Well, I guess we'll tell them together…" Phoebe took a deep breath and headed out of the kitchen

Piper and Leo were sitting on the couch talking; Wyatt was on Piper's lap giggling. "Uh Piper Leo, can we talk to you two for a minute?" Phoebe was nervous but she knew it had to be done. "Sure, let me go put Wyatt down for his nap." Piper got up and headed upstairs carrying Wyatt. Leo followed Phoebe and Paige into the kitchen.

Piper came back and sat down next to Leo at the kitchen table across from Phoebe and Paige. "Okay so, there's no easy way to tell you guys this so we're just gonna come out and say it." Phoebe's voice was tense. "Uh-oh. This doesn't sound good." Piper smirked and Leo chuckled.

Phoebe took a deep breath, "Chris is your son." "From the future. He came back to save his family." Paige was nervous. Piper and Leo were speechless. "No, but that's not possible because that would require us to…" Piper stopped mid-sentence. "Oh my god."

"We have literally tried everything short of a spell or a potion, but if Chris isn't conceived soon he won't exist in the future." "Which means he wouldn't have come back to save Wyatt." Paige was barely breathing. Piper had stopped breathing completely. "We'll, uh leave you two to talk." Phoebe and Paige stood up and left the kitchen, leaving a deafening silence behind.

Leo could barely get the words out, "Should I… um, do you want me to… go, talk to the…" he couldn't even finish the sentence. "Um, yeah, I guess so." Piper finally recaptured her breath. Leo began to orb out. "Uh, Leo wait." Piper stopped him. "What is it?" "Um, I'm gonna take a shower so just let Phoebe or Paige know when you get back." "Okay." Leo orbed out and Piper sat barely being able to move.
