Aisle, I'll, Isle – 100th post!

For some reason, I decided to celebrate Homophones, Weakly's 100th post by stranding two newlyweds on a deserted island. Don't read too much into that, OK?
Aisle – narrow path between two obstructions such as seats in a theater or shelves in a market.
I'll – contraction for "I will."
Isle – small island.
