You do all realize that this means Gilda is a subtle and devious schemer. Gilda. o_o Gilda, representative of a species which is more or less collectively off its rocker in YAFGC, and who has claims to have visions. That Gilda.
I do not think Gilda acted very subtly; still she did deviously make the situation work in the way she wanted (until Lewie got rid of Jones that is).
Regarding species; it's true that kobolds are generally portrayed as the less bright in YAFGC still that does not make all kobolds so.
In fact, I'd have to say Gilda seems quite intelligent (albeit a little crazy yeah) and we might not have seen the last of her yet! (She still has some followers if I recall correctly)
While Captain Fang might not necessarily be dumb per say but we cannot rule it out yet. Yes I like him, but I do recognize he might just be lucky as hell.
