In this story the alpha is very much alpha and the omega is pretty much the typical omega as far has his protective instincts are concerned.

It wasn’t a story out of the ordinary Non-shifter Mpreg plot and it even had an initial inconsistency in the time line that bothered me (at first Chris has no clue he is pregnant but on the same day he discovers the pregnancy (not even on his own but because an alpha smelled it) he speaks of morning sickness, of being always tired and reveals that he was 10 weeks along in the pregnancy), but it was enjoyable and well written.
