In TFA, nothing like this ever happens. When people need to run into each other, they just do it. It comes across as contrived.I find the fact that out of all the sandcrawlers R2 and C3P0 just end up being on the same one to be contrived. But that’s just me.
They were both in the same vicinity when they parted company , both are relatively slow walkers, movers so it’s not that implausible.
