It was precisely because he was cautious and had a good mindset that Luke remained calm the entire time.
He wasn't in a hurry to set off. Instead, he told Selina to use the remote-controlled android, while his clones turned into Knight and Big Dipper to meet up with the Avengers at Phil's new base.

Natasha looked preoccupied, and Dr. Banner looked dejected.
Thor wasn't here; apparently, he had gone to look for help.
Luke, however, felt that it was probably because this Asgardian prince was used to Loki's tricks, so he was more resistant and seemed alright.
Hawkeye was the most normal of them all.
