Within the context of '06, it's not out of character at all.

Amy and Elise's first encounter was with an ironic joke of neither knowing they're eyeing the same guy, and they became genuine friends and Amy was nothing but encouraging and uplifting because that's her personality as a girl in love. When Amy did learn who Elise was actually in love with, it was when Sonic was DEAD. Naturally, there was more important matters at hand.

After that, Amy asks Elise to watch over Sonic while she and the others look for the Emeralds. It was only Elise, specifically, that could revive Sonic due to being a vessel for Iblis already beforehand, so Elise can be a vessel for Sonic's soul. There's no reason for Amy to be jealous and angry, because there are more important matters at hand, Amy already knows likes Elise as a person, and Amy knows that Elise is the only one who can revive Sonic here.

The entire situation between Amy and Elise was handled very well, and makes Amy look good, unlike certain other depictions.
