Forum:The clones 3 and 4 that never returned

In double dipper the clones 3 and 4 never returned.And then when robbie lefts he is again seen with wendy so maybe he captured them and thought that dipper has another twin.Or maybe it started to rain and they desintagrated.Also it can be that they became scared like in fight fighters because they thought that robbie was going to capture them and they jumped of the bicicle, but,they didn't knew the way back.If you pay attention you may notice that no one of the clones worried about the missing clones.
