Just like the others, Leah can sense that there's something that went down with Lance and Eli.
At the very moment he dropped her name and questioned for her whereabouts, she finds herself somewhat muddled before proceeding to recall just how everything wrapped up between the three of them after their venture at the Atlantic Realm.
The true cause as for why she willilngly met him in the middle without nurturing any ire or contempt despite everything that he did to her and Eli is because he spared her memories and convinced the others to let her stay. Lance is the reason why she still hasn't forgotten how she evolved and gained courage from all the grueling events that cascaded during the battle.
Rather than saving face, it may just be his way of redeeming himself.
