YES, Keirnan should absolutely know Heron. Bros for days, that's what I want. And wow, then he should absolutely know Lena! Although of course with that sort of history on his part my instinct is to make Lena one of the girls that doesn't have a notch on the Kiernan bedpost. I desire all the friendly banter.
Aww adorable. I would be more than open to he & Lena having some overlap.
