Feel free to do as many lines as you wish! I promise you I listen to all of them in full! (plus points if you do batman lines aswell)

Cherche's future son. He has concerns about meddling with the past and wears a mask to minimize interactions -- but like the other children, he wants his parents back.
Gerome thinks meddling with the past is not a great idea and that destiny cannot be changed. However, he ends up joining Chrom's army anyways, perhaps still holding onto a sliver of hope that they can avert the apocalyptic future that he lived in.

He is a serious individual and tends to speak in a formal manner, and is always training hard to become stronger. He dislikes wasting time and feels that the others should know their priorities when it comes to winning the war. He does not like to engage in idle conversations with other members of the army, usually keeping his distance. When prodded to do so, he can give insightful suggestions and has more to say than he seems.
His supports reveal that he is actually overly shy and at times sensitive, and thus wears a mask to conceal it. He passes this off as a method to prevent enemies from reading his thoughts. Although he tries to distance himself from others and refuses to form ties with people from the past era, he tends to get lonely as a result.

The last to fall asleep at night.
