Just realized something. We've discussed previously the 'pigeon clues' that appear in Episodes 1-3 of this Season.
1: in the house
2: in the park
3: in the bell tower

(For whatever it's worth, there are also birds chirping in E03 when McAllister doesn't want to look at the view or go up the ladder.)

But then in Episodes 4-6, we have had coffee clues.
4: in the park (Kirkland & Smith)
5: in the park (Cho & PI)
6: Smith (garage) & Haffner (cafe)

I'm assuming these are bread crumbs from the writers to the fans, but I can't figure out what they mean. My best guess is that they're tied to RJ, some pigeon connection & also the way he likes his coffee.

Thoughts?
