The next morning...
"Oh my god! I'm so happy for you, for both of you!" Nicole exclaimed as she rushed in to hug her brother and best friend, "I didn't know you were planning for kids!"
"We weren't. It's just a happy coincidence." Nina replied to her, while Arnold just embraced them a little tighter, hoping to live the best moment of his life a little longer, "Okay. You two siblings talk while I decide what to cook for breakfast."
"I'm so happy! I can't imagine I'm gonna be an aunt soon!" Nicole said once Nina had left, "Who else knows?"
"For now, it's just the three of us. And I don't wanna make a big announcement about it either. The lesser people know about, the better." Arnold mumbled while glancing towards the kitchen.
"Why so? Oh, wait... I see." Nicole finally understood why Arnold wanted to keep his unborn child a secret.
