Upon mention of water, his mouth seemed to instantly dry up. He nodded, granting her a thankful smile as he told her in Arabic:
"Thank you." And then a follow up in English:

"Just haul yourself back here." After hanging up, Kyle told his new companion:
"Boss mad. No problem, though. I'm thirsty." He then extended his hand, telling her:
"Name is Kyle. Yours?"
