In the original ending Estella does not ask for forgiveness again, and does not have to tell Pip of her suffering but he can tell that she had suffered, and I think this is more realisitc as Estella is such a strong character, and she always wanted to be above Pip. I think that part of her does not want to directly confess to Pip that she has suffered, partly from the guilt of the pain she caused Pip, and partly becuase it is her nature to hide her weaknesses as far as she can.
Both the endings describe the unhapiness that Estella suffered from her husband, Bentley Drummle, which i think is appropriate as Pip was right, and he warned Estella of his brutal nature, and she agreed, but still married him. I think that in the original ending where we are told she went on the marry a "Shropshire doctor" shows that she has truely changed, as previously she would use men, and one of the reasons would be for their money. She would follow Miss Havisham's teaching to 'hate' men, and play with their hearts. In this ending we are told that the Shropshire doctor "was not rich" and that they lived off Estella's "own personal fortune." I think this shows how much Estella has changed, as she is with a respectable husband, who is not rich, and i think it is quite ironic that she is caring for a man with the money from Miss Havisham who dested men and did everything she could to make sure Estella did too.
In the updated ending Pip goes back to Satis House, but i think that Pip has moved on. In the original version after seeing Joe and Biddy together he realises he needs to move on and live his life, and unintentionally meets Estella again. In the updated ending Pip "cries out" Estella's name, as though in desperation, and makes it seem as though his heart is still for Estella and that he wants to be in Satis House again, which i do not think is true. They both appear to be very happy to see each other again and have "often thought" of each other, whereas in the original ending Pip and Estella look "sadly enough on one another."
In the updated version Pip goes to Satis House "for Estella's sake" which i do not think is appropriate as Pip does not fret for Estella any more, and does not fret for any woman. He did want to love Biddy, not Estella, but Biddy loves Joe and so I think that it is very strange that Pip does want to go and see Estella again, and is so pleased when he does see him even though the last thing Estella said to Pip was "You will get me out of your thoughts in a week," and Pip describes his business with Estella as "all done, all gone!" I think that in the original version where Pip is getting on with his life as normal, away from Satis House, and he coincidentally meets Estella it is more appropriate.
In the original ending Estella does not beg Pip for forgiveness, or tell him how she misses him, but knows that it is most appropriate just to "shake hands." In the updated ending Estella asks Pip for forgiveness again, and asks him to say "God bless you, God forgive you," whereas in the orgininal Estella just kisses the "pretty child" which i think is a lot more effective as i think it is unlike Estella to beg for forgiveness, even though she has changed, and she knows that Pip will understand that she is sorry and tells him that she is "greatly changed."
In the original ending we know that Estella understands what Pip's "heart used to be," but in the updated version Estella does not show anywhere that she feels and understands what Pip's heart used to be.
The contrast of the very end of the the two endings are very different. I think that after reading the original ending the reader is led to believe that Estella and Pip will never see one another again, but in the updated ending Pip sees "the shadow of no parting from her." I do not think this is very appropriate as i think that Pip has realised the pain that Estella caused him, and Estella realises this aswell, and they both should be apart.
In the updated version Estella tells Pip that she has "often thought" of him, and I think that even if this was true then she would not tell Pip. I think that the original ending is more realistic in that she does not go back and visit Satis House, and that she marries someone else, even if she does often think of Pip. I think that she has hurt Pip too much, and Pip has changed so much, and has realised that he can live without Estella. He was planning to go abroad, and he says many times how his biggest worry was Magwich's saftey, whereas previously all Pip would think about was Estella.
