#sand magic

[1] When Aladdin accuses Sadira of attacking them with a sand viper, in what way is a sand viper going to achieve the goal of obtaining Aladdin? I ask because up until now Sadira’s main goal was to get with Aladdin (via a sand beast, the sands of time, and sand mesmerism). So what about being attacked fits into her usual schemes? Unless by the end, Aladdin sees Sadira as a magical menace in general?

[2] When they arrive at Sadira’s home and see the other Witches of the Sand, why didn’t anyone think they attacked them with the sand viper (thereby clearing Sadira of her “guilt”)?

[3] What does Aladdin mean by “She’s tried this before.” Tried what? Pretending to be their friend and attacking them?

[4] When Jasmine points out “how they might think you did it,” she’s not incorrect to say “because it was an evil sand spell.” She’s not saying Sadira is evil, but thus far, Sadira’s sand spells haven’t really been used with good intentions. So of course the group would associate sand magic with bad consequences.

[5] Sadira’s sand magic is inconsistent, or at least what she uses to implement it. In her first episode, she uses a magical amulet; this is destroyed. In her second episode, she uses the sands of time, and in her third episode, she uses...a spell of some kind. And in her fourth (and last) episode, she uses nothing except direction manipulation. I suppose the only consistent factor is the scrolls, except in the last one. 

I guess, I just wonder what is the limit of sand magic? How does it function? Is it controlled via spells or direct control? If Sadira became more competent, would she zap green lightning when she’s controlling sand?
