I’m seeing an awful lot of weeping and fists raised skyward, shaking disapprovingly at the heavens over the fact that Rei did not, in fact, hug Nagisa. I think everyone needs a real quick reminder that in Japan, hugging and general PDA is kinda sorta frowned upon in their culture, and usually doesn’t happen, even if someone is upset or crying. Patting on the head is usually as far as it goes, but please keep in mind that usually not even parents hug their children! (Too often, at least.) Characters like Rin get away with stuff like leaning on people and hugging in public places because they ‘lived abroad’ for a while, a popular anime troupe, usually a foreigner *COUGHandusuallyfromAmericaCOUGH* who isn’t acclimated to Japan’s culture and is therefore more touchy-feely.
Hugging in public/in front of others, even between lovers, is a little bit weird. But you know what’s also weird?
Holding each other close, making lots of bodily contact, all of this is indicative of a very close relationship, and depending on how you look at it, possibly even a romantic relationship. We already know that Nagisa doesn’t have a lot of consideration/respect for the traditional, (he habitually calls everyone -chan, even if they aren’t good friends, even if they are his seniors, and he’s loud and bubbly opposed to reserved and polite) so this isn’t a HUGE surprise coming from him, but for Rei to continually touch Nagisa/allow touching is HUGE, considering how achingly formal he tends to be in every other aspect of life.
We don’t need a full-on hug, guys. Reigisa is as canon as a non-canon pairing can possibly be.
