J'onn paused when he felt a soft kick from within his stomach, lowering his head even with the slight bump that was his teammate. "J'onn? What's going on? Where am I? Why's it so dark and wet and cramped in here?" J'onn almost chuckled as he nudged the bump lightly with his snout, resulting in confused squirms as Wally tried to find the source of the nudge. "J'onn?"
"It's okay, Wally. Do you not remember what I told you before. I had to put you somewhere safe until the others arrive, otherwise you would have frozen to death." J'onn said calmly. "I apologies if it's a little cramped, but it's the best I could do. Your condition was reaching critical."
"Okay, so where exactly is this safe place?" Wally asked before wondering if he even really wanted to know. He felt another gentle nudge, which he supposed was probably J'onn checking in on him, as he investigated his surroundings as best he could. There was a fairly steady thumping sound coming from above him and whatever was holding him was very soft and warm, if a little damp and snug. He couldn't actually see anything because of the lack of light. Still, something about this place seemed familiar, but he just couldn't put his finger on it. Whatever it was, it gave him a feeling of safety like he couldn't remember ever feeling before.
"Wally, I'm not really certain how to tell you this. There was only one place where you would be safe from the cold and the animals. It is a unique ability all of my kind have." J'onn said. "You are safely… tucked away, inside my body." He paused waiting for Flash's reaction, hoping he wouldn't be to frightened by this new experience.
"I'm inside you? Like, in you where?"
"My stomach, but please don't panic…." Whatever J'onn was going to say to comfort his fleet-footed friend was cut off by a sudden hiss of pain as Flash lashed out against him, kicking and punching nearly at the speed of sound, his thoughts jumbled and clouded over with fear and betrayal. It broke J'onn's heart, sensing that. The Martian writhed slightly on the ground before coiling up as tightly as he could around his stomach, squashing Flash enough to restrain him but careful not to hurt him. "Please, let me explain. My people, the Martians, have always been able to contain those we care for in this manner with no harm coming to them. It is used as a last resort to protect our families. I promise, you will not be harmed." J'onn waited until he could feel Wally forcibly relax himself, at least physically, before uncoiling and giving him a little more room.
"You've done this before?" J'onn could hear the fear even in Wally's thought-voice.
"Not personally, no, but my father once saved my own life in this manner when I was very young." J'onn waited for a moment, sensing the fear lingering still in Flash's mind. "I swear, I would never harm you. The League is my family now." To prove this, J'onn opened his mind to Flash, letting waves of love and care he felt for every member of his new family wash over him, paying special attention to the growing fondness he felt towards Flash himself. After what felt like an eternity to the serpentine shape-shifter, Flash finally settled down, though a little residual fear lingered. J'onn blinked when he suddenly felt careful hands stroking the inside of his stomach, soothing sore spots his tenant had created earlier. Smiling and serpent's smile, J'onn rubbed back gently with his snout before turning his attention back to the fruit he'd stumbled across, hoping it would be enough for Flash since the speedster didn't need to run just yet.
