I absolutely love all of the speculation. There are soooo many directions this story can go.
And while I am enjoying the 'will she or won't she' aspect, everyone needs to keep in mind that Miles is not the only one with trauma from his past. Everything that happened to both of them has affected how they form, keep, or destroy relationships. They weathered their traumas very differently. Troy had early intervention with therapy and a supportive family. Miles did not. Also we do not know the nature of Miles' trauma yet.
I keep saying there are many possible ways this can go. Who knows? One of you may already have guessed it.
