I know that people change in the course of years and Hawaii Five Oh has been running for five years now.
But I still can’t deal with the fact that Alex O’Loughlin was so thin in S1 but by mid S3 he is getting so buff, more muscular, but also his face looks kinda softer. (Which is a GOOD look on him, but I just can’t help noticing that since I’m going through the seasons so fast. And I really liked Alex when he was thinner too.) From what I saw from S5 stills, Alex is almost getting chubby cheeks XDD (Or Steve McGarrett’s version of chubby cheeks which is how normal people look like.)
My head canon is that Steve finally is relaxing after his service and is getting accustomed to a quieter life (because I bet that compared to his days as a SEAL he thinks of H50 as a walk in the park).
