Yes. I am aware that she told him it was an aphrodisiac. But given the way she has acted in the past (she has acted crazy and apparently hurt her son at times, and acted possessive of him, etc.), and the fact that her assistant had not been given a chance to fully reply beyond "But that wine is...", there is still slight wiggle room that she had it poisoned to get rid of Regent Wang. And I am hoping that is not the case.
I am seriously hoping that when she says she is just teasing him, it means that the wine is literally just average wine and not that she has poisoned it.
