Darry: would worry; Dally may be his friend, but he doesn’t have much of a moral compass. And he knows in a way that Johnny is Dally’s moral compass. He fears that Dally couldn’t handle his urges and ends up ruining his relationship with Johnny.
Soda: would be a bit happy for them, but for the most part it would be the same as Darry.
Steve: wouldn’t understand at all; he had thought Dally was straight due to the many girls he’s bedded, then main squeeze Sylvia, and Cherry. And he just thought Johnny was just shy.
Two-Bit: Pissed off; he may joke about but Dally isn’t dumb. He sees the storm taking root in Two-Bit’s eyes when they are together and Dally knows it’s due to Johnny being a baby brother to Two-Bit. After Johnny was Two-Bit’s ‘Pony/Soda’, along with Little-Bit. Two-Bit constantly worried over Johnny.
Pony: Mad. He wants to be supportive and yeah, he’ll admit that after the whole Bob/Cherry/Windrixville/fire debacle he didn’t dislike Dally as strongly as he did before; but Pony still holds that Johnny deserves better. He thinks Dally will cheat on Johnny. And he feels Johnny needs someone who can comfort and show him emotions, which is something Dally cannot. Unknown to Pony is that Dally will sure try his best.
