2. Forrest Gump Jr.
At the end of Forrest Gump we discover that Jenny has had a child. The child is also named Forrest and is said to be his son. Soon after Jenny passes away from an unknown disease (likely HIV/AIDS), leaving Forrest Jr. to be raised with Gump. Throughout the film Jenny is not portrayed as being totally morally inclined. She is promiscuous and continually pushes Forrest away. Whilst they do have sex it is only the once and indeed was Forrest’s first and also his only time in the film.
We know that Jenny trusts Forrest unquestionably, possibly because he is as far away as you can get from her own father. He is extremely unlikely to be an utter douche to a child, especially his own. He is also essentially a millionaire and will be able to provide a child with a comfy upbringing. So when Jenny hears that she will soon pass away, who would she turn to? Forrest Gump of course. However with Jenny’s previous lifestyle what are the chances that Forrest Jr. is actually Forrest’s son? It is possible, but it seems a bit unlikely in the grander scheme of things. In fact when placed next to an alternative interpretation its likeliness is reduced even further. The fact is that it is entirely possible that Forrest Jr. is not actually Forrest’s son. He may have been the inspiration for his name, but as they were childhood friends with a deep connection he would likely be the first name she thought of anyway.
The most likely scenario is that on any one of her promiscuous endeavours another man got her pregnant, it is in fact likely that she does not even know who the father is. Upon learning of her disease she turned to the man most likely to come to her. The man who she wants, maybe even believes, to be the father. But the fact is that statistically the father could be any number of other men.
