What should be the scenario?

If TS wins against zeta, how will TS go through play ins? What should be the scenario?

3 way tie

so TS basically are at +2 round diff rn, if TS destroy zeta AND zeta win against Geng, then it will be 1-1 for all teams and TS win tiebreaker

Zeta needs to win against gen g and TS wins with Rounds
