He's still a little shy and awkward, but suddenly can be very opened. Morty suggests dances for money a lot. Dances for Mortys and sometimes for Rick's. Trying to be friendly and talk about something, occasionally fails. You just need to get him in a mood. But when he dances, he's opening all his soul and spirit and there's no more shyness anymore. And when he talks there is always thin line between being a bit awkward and too much opened
