After her intro issue in WATXM vol 1, Aaron said we would be seeing more of her...and we did...but never in the depth or detail of that original issue. This issue is the most she's in since that original issue.
And it was nice seeing her show some insecurities. Though last time i checked she could switch from Shark Mode to human mode if she wanted.
Interesting to see what comes from the Julian/Iara ship tease.
