Hank is in the Infirmary working on priming a new Monitor. These early mornings are killers, but helping people is what he does. Especially when he is avoiding the situation back on Earth.
There was a beaten on much abused once-Prince in one bed; Severe electrical burns, a heart monitor, the works. It was not a pleasant thing to look at, all those wires and widgets and gizmos tangled up with the boy. He slept deeply; painkillers kept him under, and that was probably a blessing.
His dreams were dark, when had them.
In the corner, there was a covered table, the broken body of his dog, named for the Guardian Star of The Water Margin. True to her name, she'd died defending her master. Likely, that wouldn't comfort the boy when he woke up.
And Zuko's eyes open, but there's no consciousness behind them. Even the Firebender felt that, and his body is in no condition to deal with it.
He seizes, violently, body bucking of it's own volition. Mechanical alarms begin to scream and read-outs begin to wobble... and then bottom out across the board.
