Now I know there are a lot of different opinions out there as to why it was used it in the first place, the evolution of its use throughout the series and films, and whether or not it should continue when Shane and Oliver inevitably get together. This post is meant to settle that argument.
Under no circumstances should the series discontinue the use of “Ms. McInerney.”
While I agree with the assessment that Oliver used it as a distancing mechanism to shield himself from his evolving feelings for Shane, it has also been utilized in a variety of different contexts, all of which would be lost should "Ms. McInerney" discontinue. Here are a few of those contexts:
Then there's this: Did you notice that in From Paris with Love Oliver only referred to her as "Ms. McInerney"? Not once did he call her "Shane," when perhaps it should have been used the most, especially during that porch scene!
If you remember back to when I discussed the "push/pull" dynamic of their relationship, From Paris with Love was one time Oliver "pulled" without having to call her by her first name. Oliver can pull her in with the look in his eyes if he wants to, what name he chooses to use is irrelevant.
Oliver's use of "Shane" previously, however, has often been a method for imparting great truths that speak to her heart or to comfort her like in "The Treasure Box." The only exception to this is in the pilot, where it's mostly used as a quirky joke between the two early on. Shane seems to inherently understand that when Oliver refers to her as something other than her surname that what he's trying to say demands her attention.
I'll let you see that for yourself.
Now do you see why it took so long? Some arguments are better made with well-orchestrated video montages!
