Reasonable of her. Frustrating and frightening, but reasonable.
Chris does actually calm down a bit; not that the situation is any less concerning, but having the physical symptoms damped down almost makes it easier to think clearly, like the opposite of caffeine jitters. (The yang excess subsides, although not by quite as much as it ought to.) In theory it should be possible to work together- "Combat the Wyrm" is pretty clear as commandments go but if you can cooperate with vampires on a larger goal... well. Except 'I, personally, don't die' is the exact opposite of a larger goal. Whatever's going on with the not-a-siege might be, but they've only heard one side of the story so far and it's the necromancy side. Which leads straight back to 'get out'.
If there aren't any shifters here, Chris has the advantage of surprise with any abilities they won't be expecting- any they can use while paralyzed, anyway. If there are shifters and they're hiding- well, Chris will still have surprise on their side, and then they'll trade 'captured/rescued by inexplicably nice necromancers' for 'chased by angry kitsune.' Or whatever kitsune are called when they're in China. Is it racist to not know that if the two kitsune fox shifters you know best are Chinese but they go by 'kitsune' in America?
...what to call them is not the main problem here. Focus. If the not-mages know about shifters the fast healing would have been a dead giveaway, so either they don't know or they're very good at not reacting and doing some kind of long game, so either way the plan should probably be 'play nice and wait until nightfall'. Which is definitely not just motivated by wanting a nap now the adrenaline has mostly worn off or had magic done to it. (But it's probably a good idea anyway, except for the part about being asleep around strangers of unknown motives, whatever Wen-guniang did stopped Chris from passing out but they did still run... some number of marathons yesterday. Or today. Or a thousand years from now.)
