There is an absurd amount of juice boxes in the Watchtower.
At first, they thought J'onn was the one purchasing and stashing them. It made sense. They're good for when you have low blood sugar, are dehydrated or lost blood. They're also tasty! And everyone knows how much J'onn likes sugary drinks and snacks.
But when Clark asks J'onn where he buys them, he gives him an odd look and says, "I do not purchase those."
Everyone interrogates him about who it is, but the alien is nothing but a man of his word and apparently promised whoever purchased them he wouldn't tell. It becomes a whole thing, obviously, because they won't let it go.
Bets are made about who the Juice Giver is. The younger members ask the Juice Giver for good luck before going on missions, and the older members are trying their absolute hardest to figure it out.
Then, Nightwing joins temporarily for a global wide meta human and alien kidnapping ring and is loopy from blood loss after being stabbed and stitched up. Batman is by his side in the medical area, cooing softly to him. Then, he pulls a juice box out of his belt.
Wally, who was also injured and is getting patched up on the cot next to them, gasps at the recognizable juice box brand. "YOURE THE JUICE GIVER!!" He literally screams, making Nightwing jump.
Batman's eyes widen, and he goes to shush him, but it's too late. Everyone with super hearing is busting through the door, and everyone else is following them. He sighs and resigns himself to the following chaos while helping his kid not stab himself in the eye with his straw.
