Let's remove Zwei's existence entirely, let's assume he was never introduced, he wasn't there.

So, here's how it would go:

1-Ruby is watching the Beowulf until she notices through the scope 2 WF mooks.

2-Curiosity hits her and she follows them. However, eventually they notice her and she runs away.

3-She ends up falling through the hole.

4-WBY+Oobleck are woken up by some noise. They go outside, weapons prepared, notice Ruby is not with them, and find a big hole with CR on the ground right at it's side.

5-They add 2+2, Oobleck gets the 4, fast-paced explanation no one can understand unless they watch the episode in 0.5 speed.

There. Only very minor changes, and Zwei was not necesary. In other words, nope, he was not a necessary plot device.
