Honestly I just find this baffling, they both know that they like each other - JH knows that SH wanted to propose…
When they are incapable of writing a proper episode and conflict then they resort to cliches and typical unrealistic twists. This ep (15) was such a disappointment. A real waste of time. It's already a one star less for me. I hope they'll save it in finale.
Oops! My bad! :) I actually thought it was American, dunno why. Now I see that it is co-produced by BBC America, but I'll just change it to Canadian so as to not confuse more other users.
