[Arthur's Apartment]
"I'm sure she's heard of it. She, uh...didn't exactly go with science for her first career choice. Not sure what she's doing, these days. We need to catch up. She's been gone a while, and I've been...doing other things." Like selling guns to criminals!
With that, Arthur falls silent and looks at the ceiling for a bit. "Listen, Willow, we've established we love each-other. A lot. But that means different things to different people. A good gauge for that is how far you're willing to go on behalf of the people you care about, and what you're willing to do for them."
Looking to Willow again, he takes her by the hand and squeezes it. "You've proven how far you're willing to go already. It's pretty damn far, and I appreciate that more than you can imagine." It really doesn't go much farther than shooting people. "So, I need to ask a question. How often are you willing to go that same distance for me? What would you do on my behalf if I asked?"
D'aww. It's adorable, in an awkward, possibly-interrogative way.
If it's not outright creepy, at least.
