After the snow tempest, the heat wave. The lions are dead. Seriously, they are fallen in the three's shadow and in their room and they barely move. Ferdinand screams that the lions will die if nothing is done. Caspar believes it and panicks. Lysithéa is like "fiinne" and throw ice magic on them. They end hidding in Abyss. Meanwhile Seteth runs after Claude "PUT BACK YOUR SHIRT"
Where the Blue Lions thrive in winter, they positively cannot stand the heat in the dead of summer. Ingrid pretends she's fine, but after a half hour passes, she's turning pink and is ready to collapse in the heat. Even shirtless, Dimitri, Felix, Ashe and Sylvain are all overheating and probably all roasty-toasty with a side of sunburn. After whatever summertime activities they may get up to, they without a doubt collapse in a heap once they're back indoors, and they probably won't be back at it until at least another day or two afterward. The best off of the four is Felix, who at least tans out after the fact once his burn has healed, instead of turning bright red and burnt, and then immediately pale again.
When Ferdinand and Caspar find them in a common area, collapsed in a puddle of sweat and sunburns, they nearly panic, thinking they've all passed out from sun sickness. Lysithea and Marianne are called over to help the most heat-intolerant Lions recover from their fatigue and sunburns, although not without a much needed lecture on the importance of knowing your limits in the heat and taking precautions in advance to prevent overheating.
Dedue and Mercie don't seem to mind the heat as much. Mercie is entirely as prepared as possible for the heat, decked out with her parasol and clothes that drape over her modestly yet remain lightweight and breathable, and Dedue has more of a tolerance to heat in short bursts, and can even endure it over hours at a time without too much trouble thanks to his exposure to the constant extreme heat of the workshops as the child of a blacksmith. Being exposed to the heat of the kilns has its benefits for his heat tolerance, but the longer they're both out in the heat without relief, the more they start to feel the heat waves beating against their skin. However slowly it creeps up on them comparatively to the rest, they both eventually need a break from the heat.
For all Annette's warmth of personality and her love of a warm fireplace in winter, she's probably the worst off in the heat of the summertime. She burns to a crisp in a matter of minutes, it seems, and she absolutely cannot be out in it for very long because of it.
Overall, most of the Deer are enjoying their time in the summer sun, basking in its warmth with little issue. Marianne and Lysithea have the most experience with accidental sunburns from being out in the heat, but they've also learned how to protect themselves from the heat so they don't get burnt anymore. Still, they sympathize with the Lions' plight in the heat.
Hilda, smart girl that she is, is well prepared to stay indoors throughout the summertime, but when she does have to go into the heat, she is not above roping some unsuspecting gentleman into helping her stay cool by bringing her water, providing shade for her, or otherwise taking over whatever duties that would require this "fragile flower" to go into the sun for anything but sunbathing.
Lysithea will be in the same boat as Hilda, but is more likely to hole herself up in the library to avoid going outdoors whenever possible, using research and homework as an excuse to stay indoors with little exception. Lorenz is typically there with her, barring some social outings which require his presence out in the heat, lest he disappoint his public (aka the other Golden Deer). He is somehow the first one to come up with the idea of using Lysithea's frost magic to cool everyone down after a long day in the heat, an innovative plan that ultimately ends in disaster because someone (probably Claude) pissed Lysithea off by calling her short, leading to a more targeted spell chilling them to the bone.
Leonie is the queen of warm weather, although she tends to survive the heat better in wooded areas that have plenty of shade than out in an open field like Gronder. She tends to spend a lot of time outdoors at any time of year, but summertime is when she thrives, both as a hunter and in general.
Raphael handles the heat very well, used to working outdoors in the heat and cold, rain or shine, due to his sheer stature and strength - and in summer, it's not uncommon to see him entirely shirtless while he works, enjoying the warmth of the sun on as much skin as he can get away with. Ignatz, on the other hand, while he tolerates it well, still ends up with the bridge of his nose turning a dusty shade of pink in the summer sun and needs salve to help ease the discomfort of the mild burn.
Of all people, Claude is the first to rip off his shirt at the earliest signs of summertime, from the first day the weather turns toward warmth and the sun blazes high in the sky. On his wyvern? Shirtless, and probably barely wearing pants as well. In the greenhouse? Ditto. In the classroom? Yeah, still barely dressed, at least until Byleth pulls Seteth into the classroom and he's threatened with expulsion from the monastery for behavior improper of a noble during class time. This man thrives on the warmth of summer, and will absolutely get his comeuppance when winter comes around, as he sits wrapped in five hundred blankets, sneezing and sniffling like crazy while he plots revenge on the weather.
