New Add on/Retcon changes how past stories are read?

It's amazing how one panel can change the way you read past stories. Like remember during the Johns/Katz run where it was implied that Booster had a one night stand when he was drunk? Or the more infamous moment where he gets drunk to get information from Jonah Hex? Sure the scene already reads differently once you realize how Rips' related to him but now Rips' shock and horror come across in another light. I noticed that Jurgens has Booster mention drinking a beer a few times during his run, even in the issue he reveals Jons' past in #44.

I figure it's to show that Booster can unwind and hey Guy can drink beer without turning into his dad. They already established that Boosters' temperament has him acting more happy go lucky under the influence. But this is a serious topic and it sorta changes how I perceive things even though, logically, the twins shouldn't recall everything their dad did when drunk since they were so young when he left. But like I said it worries me when these things come up with poor kids that grew up on the bad side of town. DC hasn't been too kind with the cliches in regards to those characters. (example: most writers imply Jason was always doomed because he started out as a "bad seed.") 

There's also the scene where Jon tries to guilt Michael into throwing the game for him. When he tells him to "make daddy some money" he does seem a little threatening but not like these characters are usually written. Jon mostly uses guilt because he knows that works best against his son and Booster really isn't threatened when his space is invaded. He looks upset but Michelle seems to think (correctly) that his main concern is winning his dads' love.
