Your Intelligence must be over 75% of its maximum possible value to reason with her; for you, that means if your max Intelligence is 48 or greater, you won't get that option. You can still acquire Hand So's data bead, however; after beating her guardbot in the ensuing fight, approach the left console, and if half your Intelligence plus 1d20 (plus 10 if you're a Tech Specialist) is at least 15, you get her (failure results in her destruction). Since half your Intelligence is 18, you're guaranteed to pass that check.
