It is like rain.
A few intermittent days of rain would not flood the embankment. It gave time for the banks of the river to absorb the water.
But if it rains for days without stopping, then the banks would get overrun and there would be floods.
That is the method that Loki used. Changing slightly here and there to not shock the timeline.
Jean once told her about some kind of phenomenon. This phenomenon is called timeline shock.
It refers to people who meddle in time. Meddling in time is an art.
The way Jean once described it, it is like a painting.
You make a painting.
And then looking at it, you are dissatisfied with the painting. However, meddling with time is ultimately not a painting
If it's a painting, even if you erase it, there is nothing to worry about.
But in time, it is not like you could erase the timeline completely.
To erase a timeline entirely, you need to stand on an entirely superior dimension or be able to affect it from the Source Code of time itself
