Notes

Transformers references

• The entire backstory given by Ratchet is essentially the first half of Transformers: Exodus, further solidifying the fact that it lies in the same continuity.
• What Optimus previously identified as the key to the GroundBridge power supply is actually the Key to Vector Sigma.
  • Which, coincidentally, looks more like Sari's AllSpark Key than anything else.
• Optimus calls upon the Matrix to "light our darkest hour."

Trivia

• This episode aired in Singapore on October 4, 2011, again preceding its American showing.
