Point of order: Dulcinea already knew the day's temperature would hit record highs twenty such and such minutes after it had begun declining for the day. Why do you think she took the time to open that couple's umbrella? Somebody's got to have an eye toward the future, even if nobody appreciates that sort of thing. 

"Well, anyway, you... right. Yeah. You two have a lovely evening? Ok byeeeeee~"

Heh, suckers. It's 15:14 right now, any quantifiable state of evening is [i]hours[/i] away. Niiiiiice. Gosh, she hopes this one ends in kissing. It feels, you know, well, I mean, it doesn't [i]feel[/i] much of anything when people get kisses. There's no tactile sensation (obviously!) and no pitter patter doki doki adrenaline surge that tells a person to get excited. But her Conscience Crystal turns bright pink whenever it happens, which objectively means the thing happening is good. Maybe someday she'll have enough data to understand why.

You... I mean, you know. Empirically. She signed that contract fair and square and all. 

Regardless! The Sun! Is too hot! It is behaving Abnormally! But one data point doesn't exactly make a graph, now does it? Like, yes, she could slink home right this second, where the AC is acting up again (she keeps demanding 'fair wages'? whatever that means?) but at least there are copious amounts of delightfully sun-free shadows in which to work and construct a Sun-Catching Net or a Self Altering Reverse Magnifying Glass or to construct an obsidian fortress around Fortitude and block out the radioactive hellbeast once and for all! She could do that! Obviously. She's Dulcinea d'Avingon! 

It's just, well, this could easily be because too many people got the hiccups all at once and the sun noticed and started doing it too. Or maybe a lighthouse got mad. A wizard's curse. The birth of a thousand and oneth cat (wait, no. what? ridiculous. stop looking at wikipedia during hypothesis). Or because it's still a relatively new sun it might just still be calibrating. It hasn't needed calibrating yet, but it [i]could[/i] need it. The point is she might very well wake up tomorrow to discover everything is completely and frustratingly normal. [i]Again.[/i] And more's the point, the sun being in the sky is one of those objectively good pink-crystal moment kind of things, which is why she carved out her own heart to put it there. 

So like... yeah. Further data required, and all that. So that meant the obvious next step was to take readings and find out [i]exactly[/i] what the deal is here. Later. Tonight. With cooler air and better working conditions for canvassing the whole of the Fortitude Sky. Also to be frank, it's rude to stare. You know how light changes its form when it knows you're viewing it? Same principle, but a glowing yellow orb in the sky. 

She drains her coffee in a single swig, then fills the cup again with her ice cream. Waste not. She saunters away from her third favorite cafe. And then zips back again at double speed to the tremendous consternation of a pair of beautiful lovebirds. Forgot her notebook, sorry.
