Why didn't the X-Wing pilots stick around to help Din Djarin and Baby Yoda in The Mandalorian season 2? After leaving the desolate sands of Tatooine behind, Mando is forced to courier a frog lady and her spawn in exchange for vital information, but thanks to the delicacy of her eggs, the Razor Crest is banned from traveling at lightspeed. Crawling leisurely through space, Djarin's enemies can finally catch up to him, and the ship is accosted by a pair of X-Wings from the New Republic.
After asking a few too many questions, Mando decides to hit the gas and outrun the space police, but only succeeds in crashing his ship on the surface of an icy planet. This already-perilous situation takes another turn when Baby Yoda's voracious appetite triggers an avalanche of angry spiders to descend upon the Razor Crest, damaging the hull beyond repair. Just when the stranded crew look done for, the X-Wings return to blast away the icy arachnids and give Mando a free pass. But when the bounty hunter asks if they'll assist his ship repairs, the offer is flatly refused. Why do the pilots help Din Djarin, only to then leave him hanging in the cold wilderness?
The actions of the X-Wing pilots can be explained by understanding why they stopped Mando's ship in the first place, and why they ultimately set him free. Back in The Mandalorian season 1, Djarin was (somewhat reluctantly) embroiled in a jailbreak from the New Republic transport ship Bothan-Five, and his Razor Crest was designated as the getaway vehicle. It's this connection that arouses the suspicion of the X-Wing pilots in the first place, and prompts Mando to run. He knows he's a guilty man. When Wolf Trapper and Carson Teva return for the spider shoot-out, they explain that Djarin's actions during the Bothan-Five assault atone for his guilt. After all, it was he who led the New Republic straight to the real mastermind of the heist, and Mando also attempted to defend a New Republic prison guard (Matt Lanter's Lt. Davan) from the more aggressive conspirators involved in the heist.
These actions cancel out Mando's role in the Bothan-Five incident, ensuring he won't be punished and can continue roaming the galaxy a free man. The pilots blasted the spiders not because they're indebted to the Mandalorian, but simply because that's what the good guys do. The New Republic is supposed to be morally superior to the Empire - they can't just sit idly by and allow their target to be eaten by a giant ice spider. Even if Wolf and Teva did plan on arresting Djarin, they still would've cleared the monsters first. So the moral code of the New Republic is why the X-Wing pilots save the Razor Crest, and Mando's redemptive actions in season 1 account for his crimes being erased. But when Din Djarin asks whether they'll help fix his ship, he's pushing his luck. The pilots don't owe the bounty hunter anything - he's merely done enough for his crimes to be forgiven, not to deserve a helping hand fixing his ship.
Further context is added when the pilots refer to "these troubled times." With the Empire only recently crumbling in The Mandalorian's timeline, the New Republic clearly have their work cut out patrolling the galaxy and maintaining authority. This heavy workload helps to explain why two ordinary pilots casually judge Din Djarin as deserving a clean slate, but also means they don't exactly have time to waste helping criminals fix their ships. While the pilots' response is probably fair, all things considered, it's interesting to ponder how their reaction would've changed if they (or, more intriguingly, their superiors) caught a closer glimpse of Baby Yoda.
