I mainly have more questions than comments.
But the gravity/Cybertron thing. Given that we have frequently seen mass-density shifting and size shifting it didn't bother me so much, plus it looked to be largely hollow anyway. I thought it was just a broken shard of Cybertron (because, DoTM space bridge) and not the planet proper.
Questions which I am hoping someone smarter can answer
Q1: Does the spark reside in the head, and so can Starscream be revived.
Q2: How on earth did Starscream die in the first place (Lockdown?)
Q3: What happened to all the sparks Lockdown harvested. I had hoped to see them get revived, if Megatron can come back for the umpteenth time.
Q4: Did anyone else think Quintessa looks adorable (in her shimmering metal mode) and have unnatural thoughts? #justaskingforafriend
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
