LM’s personality of wanting to connect with people

Can we take a break from the case for awhile and talk about LM’s personality?

I just recently saw this photo and I must say he is quite extroverted than we all think otherwise? Throwing an alumni party himself was actually a bold move for an introverted person we all deemed he was. Looking back, we always see comments saying he was quiet and reserved. Also, him reaching out to old classmates could probably mean he was still stuck in the past like some people say?
