After the signing of the contract, Zi gave Curtis $100,000 in cash, then told Curtis he only had three hours to deal with his personal matters before he had to start work.
Thanks to Sheyan's previous suggestion, Curtis did not raise any objection to this unreasonable request. He merely treated it as part of the $700,000 annual salary job -- or, more precisely, as the deliberate attempt of a crazy interviewer to cause trouble for him.
After going back into his house to pack up in a hurry (the explosion happened on the road outside his house), he gave his ex-wife a call to boast about his new job. He gestured that he was ready to go after that.
On the pretext of a free medical examination, Sheyan took a sample of Curtis' blood and dripped it onto his 'Chris Redfield's Lucky Bracelet'. The bloody glow of the bracelet shone even brighter, like a red agate. It seemed to be close to getting unsealed.
