Yeah, he is just Castle. Younger, cuter, slimmer Castle deeply invested in his smug arrogant Mary-Sue of a character. Full disclosure - Mal was the reason I didn’t bother watching Castle til season 4. Hmm - probably should have gone anon to say that.
lol too late :P
i find it fascinating to compare and contrast those 2 characters..i’ll wait until i finish the series to see how Mal’s characterization proceeds..he and kaylee are still my faves up until now ;)
