Separated Them - Behaviour?

I have separated my two this afternoon and have put wire mesh partition between the two of them... but since I have done this Pickle is going mental trying to break through....

Does this mean he wants to be with Twinkle? Or is it just because it is something new?

Not sure I have done the right thing...

Anyone????

I'm definitely no expert. I'd think from that that Pickle feels under thread by being separated. :? it's quite an upheaval.
