GUYS GUYS GUYS!!!!!!!!!!!! I HAVE COME TO A STARTLING REALIZATION THAT I MUST SHARE!!!!!!!!! *deep breath* The clones do not have bellybuttons. They DO NOT HAVE BELLYBUTTONS!!! To the best of my knowledge, the only times we actually seen a clone shirtless is when Rex is injured and stays with Cut Lawquane in SWTCW S2e10 and right after Echo is recovered in S7e2&3. These examples offer no evidence since Rex has his hand over his stomach in "The Deserter" and Echo's prosthetic legs arguably go high enough that they could cover his bellybutton. But! BUT!!! in S6e2, when Fives and AZI-3 visit the baby clones in their tubes, and (SLIGHT SPOILER ALERT FOR BAD BATCH) when you see the tubies on Kamino in TBB S1e1, they do not have any kind of embilical cord. They are suspended, probably in some kind of nutrient-rich jelly. See below (bbS1e1 and swtcw S6e2 respectively)
Therefore NO BELLYBUTTONS. My mind has been blown. Do the clones even know they exist?Can you imagine when they first see someone with one?? Ahhhhhh!! Now THAT is a conversation I want to hear 😂😂
Screencaps from this place here. It's a great resource that I use a LOT
