I don't think Walz needs to deliver an epic beat down or anything because Harris already did that with Trump. Just Being Normal and maybe showing (as much as you can within the confines of the format) he's done his homework and can step up if needed should be enough.

A VP debate I guess could be a game changer in this whacky year, but I'd guess more from Vance being a creep than anything in Walz's control.
