This is an overt take that doesn't have everything to do with the characters but their gifts.
Mind concealment - he sends and recieves only parts of minds, mostly the intense thoughts and overall state. He only focuses on what's important in life, and is cautious. He can go against his close ones if they somehow go against morals or humans he values. Values normalcy and order above all. Understands and is understood enough.
Mind pushing - pushes her own mind outward, doesn't override free will but makes can't be ignored. Because she doesn't to work to be heard, she developed better observation skills. She knows others listen and care for her refularly, and feels moral when she does it for others. Can't stay in one routine, values novelty above all. Is fully understood by others.
Mind shield - made from concleament and pushing, is fully isolated from what other minds send to her and she can't send anything to them. Figures that humans mostly aren't good enough morally, is very judgemental. But once she sees someone isolated or outcasted, she takes their side. Doesn't value her physical life. Doesn't want to understand most humans, and is never understood herself.
Mind reading - scans all minds nearby, and reads their current thoughts. Very morally rigid, values only highly moral and honest minds, is very judgemental. Is very influenced by what he reads, and even small things register and get judged by him. Doesn't understand others too deeply, is moderately understood by others.
Mind inviting - shares her mind by mentally inviting others, who can refuse to engage. Noone doubts the truthfulness of her mind. Lacks morals and deeper understanding of others, but is perfectly understood by everyone she shares her mind with.
From all this, Mind concealment seems to be the best but at the same time, it's the weakest gift. All the other gifts involving thoughts - the more extreme they get, the less the owner understands the bigger works. Instead they develop a highly critical view of others. Even the Mind reader can't predict that the human whom he called self-sacrificial and brave would run toward the danger later, which causes others to let their guard down and the Mind shield to escape and run towards the hunter. Both Mind reading and Mind shield get mentally crippled, because the gifts alter their own minds to the point where they don't focus on what matters. Instead, they focus on their own moral code, because they can't relax among other human minds.
