I think you mean "culminate in/at," not "cumulate to."
The "of course I will" comes a little too quickly. What, no moment of stunned surprise? She doesn't stand there with her jaw hanging open when she realizes that this guy has just proposed while she's still got her gloves on and still reeks of formaldehyde?

Author\'s Response: You can rate it however you like, but many fans of the series can point to several examples in canon which supports Nick and Nat as a couple.
