Anakin is the main character of the series. Hes not going anywhere
so a weird thing that happens in the first few seasons is that episodes are largely not in chronological order except within their individual arcs. I wouldnt recommend watching the chronological order, but it may be worth looking up where each episode takes place when you watch it because otherwise some episodes are straight up confusing.
