Is it just me, or have Bashful and Grumpy been at each others throats lately?

*spoilers*
First, in "take me to your Grumpy" Bashful insults/rudely impersonates Grumpy when not believing him about the "space carrot". And, in "Smarty Tooth" he interupts/insults Grumpy jokes, causing Grumpy to chase him....

Is this leading to something?
