Ambush
Come, give me a swift ship and twenty companions so that I may set an ambush for him as he returns. I will guard the strait between Ithaca and rugged Samos. Thus will his voyage to find his father be to his considerable cost.
Apparently, somewhere between Ithaca and rugged Samos there's a strait suitable for an ambush, but the only proper strait in this region lies between our ancient islands of Samos and Aigilips (modern day Kefalonia and Ithaki). Since our hypothesis is that Lefkada is ancient Ithaca, that can't be the strait Homer's talking about, so we need to look for another explanation.
What if Homer wasn't talking about the islands of Ithaca and Samos, but about the route from the city of Ithaca to the city of Samos, located on modern day Kefalonia and still called Same? As that would lead through the strait, it would fit the description perfectly, put an end to an age old mix-up and provide us with a new perspective to determine the location of the harbour and city of Ithaca.

Telemachos, who was just an infant when Odysseus left, has reached adolescence in his absence. He stands up to the suitors and decides to start a search for his father. The suitors don't expect him to follow through, so when they become aware that Telemachos has actually already sailed off, they decide to ambush him on his return:
