Dimitri:

Pre-skip he would stay guard at the area a bit farther from where you are regaining yourself. Anyone who tried to go to you he would distract or tell them to give you some space. When anyone asked what's wrong with you he would assure them with a smile that you are okay, just need a quick breather so best to leave you alone.
Post-skip he didn't really care much, or so he tells himself. Deal with it, was what he thought since he just dealt with it all and kept going. Though deep down he still cared; and it was obvious to others as he was still going to sit there, guarding you and ensuring all leave you alone. But now sometimes he does approach, say something cold but true, then leaves.

Dedue:

He is the one who suggests you go regain your composure, pointing out a good area he saw for it, assuring you he will keep watch and send anyone searching for you away. He keeps his word each time: standing like a bodyguard near you but not close enough to be able to see or hear you. When someone tries to go he's quick to hold his hand out to block them, maybe even against their chest to push them away if they insist, and calmly asks them to come back later. He doesn't care if anyone mocks him for it, he gladly does this as this is nothing for all the effort you put into helping them and the battles.

Back at the academy he makes you your favorite meal then brings it to your room, advising you to eat. He stays to make sure you eat at least a bite then he gives an apprective nod and takes his leave.

Felix:

At first he was always bitching about it, asking how they can have someone like this on their team. But then the battles became tougher and finally he understood as he himself began needing breathers; especially when the battles began endangering ally lives and taking a few. So eventually at times he would come join you and both just stare ahead; processing all that happened, trying not to think of how it could have gone better as it has happened so the "what if" and "but" are now useless. Sometimes he wraps his arm around you and pulls you against his side, muttering you did the best you could. So you rub his leg in appreciation and thanks then answer back 'so did you', which makes him silent for a second then nod.

Sylvain:

He wants to comfort you but you clearly want to be alone, which was definitely obvious as you went to an area with no one around or where anyone could see you. So he patiently waits a bit farther away, searching for something. When you return you always have him aside you, asking if you are okay then presents a type of flower he found, telling you with a smile that he thought this flower was almost as beautiful as you. You take the flower, mumble a thanks, then go to the group to return to the academy.

He always assumed you throw the flower away on the way back, but then one day he walked past your room while it was open and he saw a flower he had given nicely presented in a little glass filled with water. His heart almost jumped out his chest from how quick it began beating, with a goofy smile forming on his reddening face.

Ashe:

He was always worried at first but eventually he kind of got what you went to do. So he began preparing a small bag with food, water, and a small diary. So when you go to rest and recover before you continue he hurries to you, nervously telling you to take this. He worriedly waits as he tries to help the rest with things. When you return he asks you if you are okay and if the bag helped; so you hand it back, nodding then call all together to continue the journey. He's very happy whenever the bag gets returned with the water gone and food eaten as now he feels better knowing you have some energy back in you. He never looks in the diary so he doesn't know if you use it to scribble down your thoughts or not, but that's not his business so he stays out of it.

Ingrid:

She always gives you that sympathic little smile when she sees you go away to go be somewhere alone. One time she came across you just lying on the grass, staring up at the sky, hands cut from clenching and pulling the tall grass. She wanted to hurry over to take your hand and tell you to stop it, but she decided to leave you alone and quietly went back to the group instead. When you came back she handed you a bandage, saying cuts get infected quickly out here.
When you return from these moments she gives that little smile again, a bit awkward and unsure what to say or do so she sticks to the rest. But back at the academy she comes to you to invite you to have a meal with her or to hear how you are doing.

Mercedes:

She will go to a horse with bags full of supplies. She searchs until she finds what she needs. She patiently waits until you emerge again. You always look so much more tired than when the battle had justended. It always makes her so worried for you. You just look so done and as if you could collapse and fall asleep. So she's quick aside you, gently asking how you are now before suggesting for you to eat these sweets she found to regain some energy to make it back to the academy. She's aside you the whole way back, trying to make light conversation and ensure you are okay.

Back at the acamedy she advises you to go rest. When you try to refuse she gets a firm tone, now not advising but telling you to rest then assures you she will keep an eye on the others so don't worry and go relax.

Annette:

She tried to be extra energized to keep you energized, but that dies down when she sees it doesn't do much so instead she awkwardly apologizes and moves away to leave you alone. She will explore the supplies bag for anything that might help. She forgets her own tiredness to stay focused on helping you. It's always something different she brings you; usually just food, water, extra/clean clothes, a book. One time you returned and suddenly she put a flower crown on your head. You gave her a questioning look, which caused her face to turn red as she admit she couldn't find anything useful so she made you a flower crown. On the walk back or to the next place she keeps rambling to you about things, though halfway falls silent then nervously asks if you are okay.
