Here's a picture of Joonas I took of him last month at Comic Con:
Dude was real down to earth, and he was real easy to talk to. When I wished him luck on his future endeavors, he responded sort of awkwardly which lead to another conversation on how tight-lipped he and cast members had to be in regards to current and future projects. So he didn't want me to leave with a certain impression. But let's just say that the more we spoke, the more we came to a mutual understaning on things.
