Oh Sara, how absolutely sad... ! Reading all this made me cry... Tinky and Jupiter were so beautiful together....! You must be crying your eyes out now..
I don't know if this makes me a bad person, but I wish so much that Jupiter will miss Tinky so very much and act soooo sad, that your sister will decide to let him come back to you...!
Be strong Sara, we are all here to chear you up. Please keep us updated ...
