I really like 1A, 5A, and 4D, although I think that last one should probably be Green monster's muffling Ariel's screams because as is, it just looks like SHR(I)EK.
For 3d i had thought LT was short (brief) for lieutenant (second (in command))... and a was A and reader was TEXT... merlin fails yet again sry but thx for the puzzle
