I know we dodged a bullet
You didn't, there was no bullet.
1. Hydraulic system failure.
2. Isolate fault
3. Return to airport, burn off fuel until maximum landing weight is reached
4. Land.
While not a common fault, it is something that all of the crew are trained for. Your 'chance of death' was increased from "phenomenally unlikely" to "exceedingly unlikely" while they isolated the fault. After that it's service as usual.
Man up.
