I don't know - not a fan of the scene. I don't know, why the tadpole is connected to the console, but not to the elevator or the healing stations.
It could be because her pod requires extra security. I think anyone including thralls would need to use the healing and the elevators in an efficient manner. Probably our pods would have had some type of console involved but they got destroyed.
Good. The path to evil should be easier and more immediately rewarding. Otherwise, no one but sadists and/or idiots would choose evil.
Not too sure that our characters (as players we know too much) would consider the use of the tadpole at this point as being rewarding, we know nothing about what it will do to us. I think that the type of characters (usually good aligned) who want to save anyone in distress would be more tempted to use it here. An evil type may not see the risk as worth it because self preservation is more important than saving some random person. If they added something about us sensing some great power coming from inside her pod then it might tempt the more traditional evil types to save her because it might actually be worth the risk.
