Wiidows personality? Key differences from other Kwamis. I can imagine if Audrey unintentionally ticked Wiidow off she would make webs in her wardrobe
I can imagine Wiidow being, like, a more snarky/sassy/morally ambiguous version of Charlotte from Charlotte's Web, if that makes any sense? Another comparison I could draw is a more compassionate/less malicious version of this one character of mine, Hannah (my version of the Handaconda from Paper Mario: The Origami King)? So, like, Hannah meets Charlotte.
As for differences from other Kwamis, well, she hasn't had a Miraculous to let her truly physically interact with the real world until now, so that's something to keep in mind (she's probably very excited to be fully semitangible now, even if she displays her enjoyment of this in a very calm way). Also should be kept in mind that she doesn't have anywhere near as many bindings on her as the other Kwamis (like being forced to obey the holder, or being unable to share things like names), due to Chloe being inexperienced (and also probably wouldn't end up doing it even if she could). This also means the powers she grants are far less limited, which is both an upside (more uses and less need for recharge) but also a downside (less limiting means more likely for the user to burn themselves out quicker).
Oh, and Wiidow would probably be the type to just...web up Audrey's clothes even WITHOUT provocation.
