So I don't know how much I really followed the prompt, but I'm rolling with it.
It's a 'what if' of Dimitri surviving the caves and the walk back to the academy after.

Delirium

I dragged Dimitri along with me, he was aware enough to put one foot in front of the other but that seemed to be where it stopped. My mother and I managed to fight off the Strigoi that had dragged him down, I had slashed my stake over the Strigoi's face so that he released Dimitri's neck.

When I finally got him back onto his feet I could see he had also hit his head, blood ran down his right side from both the head wound and the bite on his neck.

We were moving as quickly as we could, the others outside the cave had already been clearing off, thinking we were dead. There were a lot of guardians that were injured from the fight, I waved my mother off to go help them while I shouldered Dimitri's weight. His arm rested over my shoulder, leaning against me as he struggled to remain upright.

The sun was still in the sky, though it was setting fast and we still had a lot of ground to cover.

"Come on, comrade," I encouraged, my arm wrapped around his waist to keep him standing. His shirt had ridden up a little, my hand pressed against his bare skin. Just this small touch made me think of what happened in the cabin.

Every part of me wanted to believe that what he had told me before we went to the caves was true, holding on to that hope is what kept me going, and what gave me the strength to return for him.

"Roza," His voice was slurred, yet thankfully quiet, "what if we made a mistake?"

My eyes shot to his in disbelief. Was this really where he wanted to have this conversation? "What do you mean?"

He blinked a few times, licking his lips as he opened his mouth to speak a few times. "There are so many… reasons that this is bad."

My heart clenched, angry tears gathering in my eyes. "I don't want to talk about this right now."

He was silent for a couple of minutes. "But I love you so much. There are more reasons why… You're so beautiful." I could hear the smile in his voice, feeling whiplash from how quickly he changed his tune. "And that dress… I like you in black."

I glanced up at him, eyebrows raised, "Are you okay, comrade?"

His eyes were unfocused, his steps faltering. "And red… you look nice in red." His face dropped closer to mine, pressing against my hair with a happy sigh, "My Roza."

My cheeks were heating up, trying to shift him so he wasn't as close. The last thing we needed was someone looking back at us and questioning what was going on. "Not here, okay."

My words did nothing to deter him, "I love you, so much, Roza. So much it hurts sometimes."

I ducked my head, focusing on where we were going rather than the effect his words had on me. He must have hit his head harder than I thought. I had seen this happen before in training, someone would hit their head and become loose-lipped.

"Where are we?" Like a switch had been flipped, Dimitri went from whispering sweet words in my ear to complete confusion.

"We are walking back to the academy. We're almost there."

"What happened?" He shifted, almost pulling himself from my grip, "My neck…"

I adjusted my hold, needing to put more strength into keeping him walking forward. "It's okay. You got injured but you will be okay." It seemed my words soothed him a little, leaning against me again. "Just a bit further and everything will be okay, Dimitri."

His head dipped down to my ear, "My Roza."
