I'm new to the forum, so bear with me :). I just had to join in after playing TWD and reading all the awesome commentary.
I wanted to propose a ending for Ep. 5 that I have not seen anyone post yet:
I think that (despite how much I would love to believe otherwise :)) that Lee will indeed die from the bite he sustained at the end of Ep. 4, and more than likely he will shoot himself after saying his goodbyes to Clem. Here's the twist: Remember when Carley gave Lee the recorder in Ep. 2? I think that Lee has been "recording his thoughts" like Carly recommended and in the end he will either give the recorder to Clem or she will find it on him. The final scene will then be "What Remains" of Lee as you get a replay of the decisions you have made and his thoughts regarding them and the situations you have endured. The last recording will be his farwell message to Clem and him encouraging her to stay strong. Obviously this will be an emotional exchange, but it could also be a perfect precursor to the next season :).
Either that or Lee accesses a secret armory in Savannah somewhere and manages to acquisition numerous assault rifles and the final scene is everyone getting on the boat watching as Lee faces the Zombie hoard alone with "Escape" by TDWP playing in the background. The last cut scene is Lee turning to the goup and saying "For Clem!!!!" and charging the hoard in one final act of courage. \m/
Either way, it will kick ass :)
