Prompt: Reasoning + GrayLu - sassyhazelowl
Reasoning
When it came to Lucy, Gray had come to learn that it was best she just get her way. Most of the time it worked out for the best, because she was really one of the only ones on Team Natsu who had the capability to think logically and use her actual brain (unlike Natsu, and also himself included some of the time). But for the rest of the time, Lucy getting her way with things just made Gray's like much more pleasant. She could be extremely cold when she wanted to be.
That much he'd realised rather quickly. (But did he love it? Hell fucking yes, he did.)
Regardless, there were times when Gray was convinced that there wasn't a single logical or reasoning bone in Lucy's body. Like when she seemed to think that she could handle standing outside in the worst snowstorm that Magnolia had seen in two decades just because her boyfriend happened to be an Ice Make mage and she could supposedly handle the cold now (and that little adventure had only ended up with a visit to the infirmary where lots of warm tea and blankets had been awaiting her).
But of course, Gray was also very much convinced that the odd moment where Lucy seemed to forget how to use her brain correctly was all because Natsu was her best friend. His stupidity had worn off on her - on all of them, really.
And still, odd stupid decisions or not, Gray still loved her. Especially when she thought she could handle being turned into a human popsicle.
