HELP ME PLSSS Dally runs out "like the devil was after him" when he finds out Johnny is dead. According to Pony, why is Dally having so much trouble handling Johnny's death?

Johnny said a lot of nice things about Dally and, while they didn't know each other well, Dally thought Johnny was pretty cool.

Johnny was Dally's cousin and they were very close.

Johnny was the only one he truly connected with and the only thing Dally loved; they were best friends.

Dally is very emotional and actively gets upset about most things​
