I'll grant that, but not in this extreme and not after what she's been through. Omega Ridley anyone? that version was scary as **** and here comes purple ridley (who is fabulous) and suddenly she shits bricks.
It wasn't so much his form that triggered her PTSD, more like his existance to being with at this point in the timeline. Most of the time she has defeated Ridely, there has been a body and the space pirates to bring him back to reign more terror, or he simply escaped. This is how it was with Metroid-Metroid Prime 3 (Again in a time line sense.)
Super Metroid however, the whole planet housing the remainder of the Space Pirate forces and Ridley's body was destroyed. This was alluded to in the beginning of Other M. He was finally gone, for realz this time. But then obvious, the Federation needed Bio-weapons, and with the biological material they kinda went ahead and "Acquired" from samus, foolishly made a Ridley clone.
So now, in a rain of fire and brimstone, her childhood nightmare has come back from what should have been his final death to continue tormenting her. It seemed very appropriate to me, Hell I probably would of been offended if she had reacted in a lesser of a way.
