4 placements in Scorpio

I know someone with a moon,mars,saturn and pluto all in Scorpio.
On top of that he has a venus in Pisces (more water) and a possible sun pisces (don't know his time of birth but I'm hoping his sun is in early Aries for the sake of sanity)

How emotional is this person? And how much do they freaking hide it and try to control it? It's crazy.
On top of that he has no air signs at all so detached logic is not his thing.

His north node is in Gemini. How hard is it going to be to follow that node with no air anywhere?

People with alot of Scorpio tend to hide their emotions from the outside. Yes, he's probably very emotional but my guess is he doesn't show it. Sometimes it's a struggle but depending on how old he is and how well he is able to deal with his emotions he probably has a system down. Having alot of water (especially Scorp) we are quickly able to set up a wall to defend the soft emotions.
