He'd do his best? The look Cade gave Zacharias was clearly doubtful, but all he said was, "You do that." He started to leave, but paused and took small package out of his cloak. It was one of his reserve rations that he kept on him at all time - just in case. He pulled the tab to activate it and warm the food inside, then tossed it through the bars to Zacharias. "It's designed to not leave a trace, so it'll disappear in twenty minutes. Eat fast."
That done, Cade left Zacharias to eat - or not - and turned his mind towards the case he could do something about: that of Dmitri Zurlo.
