Hey...wrong place, bro. This is the Manga. So you mean GREEN and RED.Actually, now that you mention it, I wouldn't surprised if Prof. Oak got sick and had to be confined to bed. Or, maybe, Gary will be in an accident and that causes Ash to return to Pallet Town.
Hmmm...
Maybe someone important will die (Like a Dexholder)
Like Yellow...
Or someone that will cause angst and stuff.

Y-you...want Yellow to die? T^T
