Hello and welcome to RWBY. just follow these steps to be cough up to current without watching the first two seasons.
so, ok here I go. If yo want to get into the series of RWBY and want do not watch the first two seasons (Have no idea why and you should to get the whole story line) than follow this list.
First watch THE TRAILERS!!!!!! even if you watched all the seasons the trailers give A LOT of back story!!!!!!.
First watch the red trailer then white then yellow then black.
you can watch them on youtube or the Rooster Teeth website
next watch the series on netflix (if you have it) if you have netflix you get a few deleted scenes added in. If you do not have netflix watch it on youtube.
Next listen to these three songs. And also take time to think about them.
First: This will be the day
second: Time to say goodbye
third: when it falls (currently it is the season 3 theme song so look up the opening for season2)
next listen to the World of Rementant series, this explains a lot of things.
Once you have digested this you can move on to watching RWBY without watching the first two seasons.
I however REALLY RECOMMEND YOU DO BECAUSE A LOT OF DEVELOPMENT HAPPENS IN THE FIRST TWO! BUT IF YOU ARE TOO LAZY THEN YOU CAN DO THIS AND BE SEMI COUGH UP TO CURRENT EVENTS.
But it only takes like 6 hours to watch all the RWBY episodes up to now excluding the trailers.
You have just completed the start to RWBY guide. Enjoy the addicting and awesome series.
Also I am sorry for the hours of rewatching episodes in anticipation of the next episode.
