The Bet

"If I'll tell you what it is, will you promise to not tell grandpa about it and put me in an awkward situation?"

"Yes I promise" Rachel was worried as to what it is going to be about and prepared herself for the worst.

"Also you won't feel awkward after knowing it, promise me that"

"Yes I won't" she almost shouted at him as he was scaring her even more, so she expressed her thoughts, "Daniel you are really scaring me now."

"They just wanted us to spend more time with each other, it seems our grandpas didn't give up on the idea of getting us married." 

Daniel casually answered her, he thought this would be the best reply as she will stop worrying about the actual thing, if he would say there is nothing then she would definitely not believe it as she knew her grandpa very well. Daniel also knew their grandpas are still rooting for them, so he found this lie to be more plausible and believable.
