Gunnar is already far from home, so if it were to come down to a shelter at home order, he wouldn't really be able to go all the way home. Assuming flights were restricted to a lot of locations (and even if they weren't, it would probably be inadvisable to go through high traffic areas like airports), he would end up staying in Tampa and isolating in his apartment with his dog (and his roommate, if he's in a similar situation). Honestly, it wouldn't be easy. He's a very active person, and not having practice to go to and games to play would be rough on him, so he would try his hardest to find other things to occupy his time. He would probably spend a lot of time facetiming with his family in Sweden - he has a lot of sisters, so there would probably always be somebody who could talk to help him keep his brain busy. He would take up some hobbies (maybe get a little better at cooking and baking, which he already dabbles in casually). Most of all, though, he would try to keep from feeling guilty about missing hockey so much when so many other people have it much worse and are actually in bad health or other danger.
