Flickerwisp enters the battlefield and Silverback Ape is targeted and exiled.
Flickerwisp is then sent to graveyard with Murder during that same main phase.
At the end of turn does the Ape return?
I think this is a "yes" but I'm not sure because the spell reads: "Return that card to play under it's owner's control at end of turn". It doesn't say "..from the game then return that card to play...".
Yes the ape will return. When the Flickerwisp's ETB trigger resolves exiling the Silverback Ape the delayed trigger to return the Ape is set up so that no matter what happens to the Flickerwisp it will return.
The Silverback Ape will return. Flickerwisp will create a delayed triggered ability ("At the beginning of the next end step, return the exiled permanent to the battlefield under its owner's control."). This triggers whether or not the Flickerwisp is still in play.
