Because of plot device x Poe ends up in the past at the time of the rebellion against the empire and joins them of course. He gets to meet all the people that are legends in his time when they were just a ragtag army (~in need of a shower~).
Poe's in Leia's corner all the time and fanboying over how badass she is even though she's only 19
And all that time travel stuff gives him a headache on a good day (should he get between Leia and Han considering what will happen in the future?) when he meets Luke Skywalker. Earnest, cute, dedicated, nice Luke Skywalker. Poe's a lost cause from the moment Luke smiles at him.
When Poe ends up back in the present time again, Luke's happy to see him because for decades he assumed the love of his life was killed by the empire
Bonus if Poe meets Shara and develops a friendship with her (which leads to Kes being a bit jealous)
