Things change. Situation is different than before, different tactics are needed. I'm a Specialist Lydia, its my job to be adaptive. To think tactically. It was better originally to stick to my own devices. Kept me alive this long. Now its better to work in numbers.
And honestly, what would killing any of you gain me? If we somehow wind up back in Lawrence I'd rather not deal with a bunch of angry loved ones. If you die to stupidity then frankly, sucks to be you. But I have no reason to kill any of you.
