If Gwendolen accepts me, I am going to kill my brother, indeed I think I’ll kill him in any case.
I find it interesting that he only thinks about killing his "brother" if Gwendolen accepts his marriage proposal. If he is willing to get rid of him that fast, why did he need the second identity in the first place?
You have invented a very useful younger brother called Ernest, in order that you may be able to come up to town as often as you like
This is interesting and makes me feel like there is something that Jack is trying to hide. This could be something work or relationship related, and he doesn't want the people from one place or the other to find out about his secret life. This makes me think that he is quite popular because if he was a nobody, then he wouldn't have to try and hide his life.
I have often observed that in married households the champagne is rarely of a first-rate brand.
This reminds me of some of the past readings that have been presented to us. A lot of them deal with social classes and how certain people are superior to others (Rich people, white people, and men over women). The way that drinks are portrayed here shows that servants aren't supposed to drink . the same thing as the people who they are serving for, because they are not seen as equal. This is similar to how people of color and women are shown in society as not having the same advantages as whites or men.
