I wondered what Lindalee would make of “A Town Called Mercy,” which has somewhat more mature and complex themes than the previous two episodes. She gets the gist, but does seem less enthusiastic about this one. As always, SPOILER ALERT:
A puzzle about this episode: why is Amy suddenly so incompetent with guns, when last week she and Lestrade took out a whole pack of velociraptors with their rifles?
In regards to Amy and guns, you could argue that the rifles were more advanced and therefor had better protection against misfiring as well as being easier to use. Whereas the compartivley primitive revolver made her lack of firearm competence more evident.
My thoughts were similar to Maxx – Amy might have gotten rather experienced with spacey wacey futury guns, and the old fashioned sort surprised her with how easily it misfired.
