and Shen Wei was barely managing to stay above water with the battles he was already fighting without having to contingency-plan for ZYL's contingency plans as well

Ha! That's the perfect way to put it. And I'm definitely Team Shen Wei's Sacrifice, too.

(Also, ZYL's sacrifice afterwards - he'd have fought Shen Wei tooth and nail if he'd known what he was planning, but in the end ZYL makes the same choice to sacrifice himself for the greater good, and I think in that moment he fully understands why Shen Wei did what he did.)
