Updating a headcanon [SPOILERS for "Where The Apple Lies"] · 3:11am Oct 18th, 2016
So, my headcanon from Breaking The Sound Barrier is that Mac is a stallion of few words due to a speech impediment. How does that fit in with the episode where he talks a lot? Well...
First, we have smol Mac.
Then we have Late Teen (early 20s?) Mac.
