I am in the drug store and Clementine is attacked by a Walker. I stumble down, and try to reach her, yet I am not fast enough and she is saved by someone else instead. Afterwards, there is a notice that Clementine will remember I did not save her. This makes me think it is possible to save her myself.
Is it possible to save her by myself? If so, how am I supposed to save Clementine myself?
