I realized something when I watched "Out of his Head" again. We never saw Breakdown return to the Nemesis. Given, we never saw him or Knock Out explicitly return in Deus ex Machina, or on other occasions. But imagine this: We last saw Breakdown being blasted away by the destruction of Starscream's DEATH DISPENSING mega cannon. This is the Arctic - which has proven capable of freezing a Transformer to death (Prime, Arcee, thr Scraplets). However, Breakdown isn't dead, just in stasis lock. And let's assume MECH was observing the situation from afar - after the theft of a vital lens to a telescope. MECH sees the Autobots return to base, and the Nemesis take off. But where is te big blue one who makes cracks in glaciers better then a saber tooth squirrel and an acorn? MECH finds Breakdown, and imprisons him just like Sector 7 did with Movie Megatron. And since they took a scan of Optimus' schematics, and as Silas said, found out what makes Transformers tick... Bingo. So that's my theory. Breakdowns dissapearancr was not necessarily from budget or lack of screentime. He disappears because he will be found by MECH, setting up for next month's episode, "Operation: Breakdown". Thoughts?
