Chika and Shito became that much closer this episode and really solidify the kind of partnership they want to have. Chika affirming once more his need for money is liked to his will to live. Thus, even knowing Shito is born a zombie, there's something profound in their hand exchange afterward as Chika is silently asking him if he wants to live or not, and that his background doesn't matter to him. Heck, Shito himself has mentioned in past episode that living is signify by the bonds made during their lifetime, and so by asking Shito to call Chika his name, he is also asking to live for him. The balance between humor and horror as always is great.
