In the book, Tangerine, how does Luis treat Paul when he comes to visit the tangerine grove?

Luis was welcoming when Paul and the others visited the tangerine grove.

Luis smiled. He had large teeth inside a large head. He had a strange shape, too—bony and muscular at the same time. His arms, his legs, his whole body were like thick rope.

Luis said, "Good to see you guys." His voice was soft and seemed accented more than Tino's or Theresa's. He walked ahead of us, limping as if his left knee would not bend. He led us out of the Quonset hut toward the weather-beaten trees on a hill north of the house.
