It's only natural to worry. You're in unfamiliar territory. It's one thing when you're the uncle, or the godfather, or the friend. It's totally different when it's you in that position. You're responsible for this tiny little life that's going to completely take over any time now. And that little life is going to require your direct assistance for everything for about the next year or so. It's overwhelming. I don't think anyone is ever 100% ready for it.
But you're going to get through it. And this isn't the end. It really is just the beginning of a brand new chapter. You guys just sort of skimmed through the 'Penn and Chase' chapter and went straight into 'Penn, Chase, and Baby.' And you two will figure it out. Or I'll have to kidnap the baby and you two will be locked in a closet until you do while Lyric and I teach our new little mini all sorts of things that will drive you insane. Like the Wonder Pets. Seriously, Penn. Pray that they go off the air sometime in the next year. It will save you a lifetime of echoes of "What's gonna work? TEAMWORK!"
Honestly, I wish that I could say that 100%, without a doubt, such a thought would never cross her mind. But if for some crazy reason it does (even though I don't think it will), you know that we'll find a way to get through it. Penn, I love you. And because I love you, I'm going to tell you this. Stop focusing on the "what if" scenarios that end with Chase leaving. Focus on the immediate. You love Chase. She loves you. And you two are having a baby. Together. Stop worrying about a couple of months from now. A couple of months from now, the world could end. The sky could fall and everything could be over and you've wasted all this time worrying on what could (and probably won't) happen instead of focusing on the great things in your life.
Everything will be great again if you just let it.
