For all of the talk about the her scary sharp teeth, I think the meek alien girl is the one who face more danger from the taller species with black hair and aggressive behaviour
Not to mention it's 2 vs 1.
Necessary reminder that she's the obligate carnivore with a constrictor snake for tail in the room with two wholesale noncombatants, and that eg. dogs rather smaller and less formidably armed are perfectly capable of mauling and killing full-grown humans.
Now obviously it would be terribly stupid of her to inflict grievous bodily harm on them (nevermind now that she seems quite fond of Scientist Lady) since she's presumably stranded on a planet full of other humans, and vice versa the latter would be quite imprudent to not handle her with kiddie gloves.
Don't want to look like the equivalent of, and duly get analogous treatment as, 19th-century savages who ate the missionaries/shipwreck survivors/explorers if and when someone comes looking in the interstellar analog of a gunboat after all...
