OMFG, THERE'S BOB/BRIAN \0/ was pretty much my first thought when I saw this come up.
Then it was, omg, baby. Then extreme amounts of flail, of both happy and sad aww huggles type, in various places. Ending in Awwwwww he's happy bless them both.
I'm all sort's of in love with this fic. And bless Patrick and Pete too.
Very lovely ♥
