Wei Wuxian follows along, more because he is being guided versus actually knowing he is being pulled. This is the first time he has used the shapeshifter ability since it became permanent. At least it was the first extensive use of it. Never before had there been any side effects of using it and of course he never expected there to be any this time either.

But he doesn't say a word, not even knowing where or who he is at the moment. His feet just taking him forward as if he is sleep walking. At least this happened in the presence of Lan Wangji so no matter what he won't be ending up somewhere random in the hotel or in the presence of someone who can't be trusted.
