Grid differs from the average xenomorph. Learning at an increased rate to her broodmates, Grid is better able to understand and make sense of her surroundings and experiences. Even after repeated encounters with the Predators she survives, and even kills several, while her broodmates are not so fortunate, in due part to the fact she can look at a situation and decide if she'll have the advantage or not. Observational learning, problem solving, and basic reasoning all come to her easily, and make her a dangerous opponent in the field. She knows a Predator can fuck her up bad, while a human makes for much easier prey--unless they're armed, and oh boy does she know that guns = bad. If she realizes she's in a position to be harmed she has no issue with sitting back and letting her broodmates rush ahead, or even with retreating outright. Given the opportunity, and if she's permitted, she's just as happy to hang out in the background and simply observe, learning and observing with an almost childlike curiosity.

Her Queen was the most important thing in her life, being mother, master, and centre of the universe for Grid. Her wants were the wants of the entire colony--except, perhaps, for Grid. Slightly more aware, and just that much more independent, she possess a heightened sense of self-awareness that would have likely caused her to be killed or outcast from the colony had it continued to develop. Instead her colony was blown up, and her mother was chucked into the antarctic ocean to die. Now alone, without the connection of her colony and mother, she has the opportunity to develop more or less as an actual individual.

Grid has no issue killing and consuming other beings, obviously, as she still retains her very strong 'us or them' mentality, and anyone not a xenomorph is very clearly an Other in her eyes. The importance of the colony in her life, firmly hardwired into her skull through generations of evolution, is that only her kind is important, and everyone and everything else is either an obstacle or potential food. That said, she is now more open to explore and interact with these Others in a different capacity, since without a mother, without eggs to guard and the need for brood victims, what need is there for her to kill or abduct every creature she comes across?

Lost without a colony to give her purpose, a sense of egocentrism automatically sets in and her own survival becomes the most important drive. All her actions and judgements are made based on her own wants and needs, and the ability to empathize with others is currently quite beyond her grasp--since anything other than another xenomorph is automatically judged as something less, similar to the way a human might look at a chicken.

Of course, it's probably worth mentioning how her age factors into everything. Given how young she is, Grid has an extremely limited scope of life experiences to draw upon. All she knows is a few frantic hours with her sisters in a cramped pyramid under a fuckton of ice. Everything is shiny and new and strange to her, and likely will be for some time.
