Do we trust Van?
In the S3 premiere episodes, are we sure that Van didn’t set Tai up to get caught by making her feel bad about what they did at the restaurant and then purposely cutting her foot? Tai had repeatedly told Van to stop leaving her dishes on the floor, and I don’t think Tai saying it to Van was simply a cute but annoying couple moment. I think it was a clue that Van should have known better and perhaps did. I suppose it also could have been a purposeful red herring.
Tai’s abandonment of Van caused some deep resentment, and Van seems to be up to something. As others have pointed out, she definitely didn’t go to urgent care. And it looked like Van really needed that beer when they were reunited that day. We saw what Tai was doing. What was Van doing?
Also, all of this makes me have some doubt about Van even having cancer. I’ll need to do some rewatching, but I remember feeling like Van has been acting suspiciously since we met her.
