In chapter 2 of the outsiders, why does dally look sick now (during the flashback where johnny got beaten up heavily by the socs)? i can't find the answer anywhere!

I did this too in 7th grade, I was looking in the book again and I'm not sure what version of the book you have, but mine is with the weird cut pages and in page 33 I saw the line "why did he look sick now?" addressing Dally, and I read the whole page and it said they found Johnny beat up really badly. And it also says Ponyboy was confused why he looked sick since Dally had seen people beat up badly, but making an inference it must be since he knows Johnny and is closer to him, so he must've been beat up really bad.
