Frankly, a lot of Elsa’s behavior might be explained by cough medicine. Especially if it involves whiskey (or, as the husband suggested, laudanum).

As I tend to headcanon Elsa as having a really fast metabolism (because of the magic), and having a decent alcohol tolerance due to probable exposure to wine and spirits while young, that cough medicine is hella potent.

On the other hand, old time-y drugs were not fucking around:

As I said, high as a fucking kite.
