The Lone Ranger lie

There are two "flashback" episodes of The Lone Ranger that explain how the Ranger came about being, "The Lone Ranger."

One episode states that the Ranger was crtically injured (in episode #1?) and that Tonto came to his aid and nursed him back to health and therefore they became companions.

However, it must be noted that Tonto didn't come along until episode #12.   That is a passage of either 12 days or 12 weeks (depending on how you want to look a it) and since The Lone Ranger is not a serial, we can assume it's not 12 minutes/hours.

In other words, the script continuity is afoul.
