With the sharing his story as to what happened to Sizhui, at least, the one growing up in his world anyway, so it should a mirror of Sizhui's journey in their version as well. It's a topic he should bring up for an interesting discussion with the other version of himself.

Empathetically, "Wei Ying, don't be hard on yourself. I think one day he'll remember that had happened in the past on his own. For now, I never brought it up because if I did, then I owe him an explanation as to why you're. I want him to understand on his own. Remember one's past is a journey of self-realization...and I mean that for you as well."

The iced tea helps with the cool doown. After a pause, a beat, "Be gentle on yourself, Wei Ying."
