Sometime later, having had her fill, Avalina calmed down. While she was embarrassed for her actions, no one blamed her. After all, she had no control over herself after the sudden evolution.
Ashton was by her side the entire time. It was during this time something weird happened. While Avalina was chugging blood, she suddenly threw it all up.
A vampire throwing up blood was unheard of, as unlike humans, while a vampire could 'satisfy' their hunger, they could never fill their bottomless stomach. Keeping these reasons in mind, everyone knew something was off.
Without wasting a heartbeat, Ashton checked Avalina's stats and low and behold; the reason was flashing brightly.
Avalina had undergone some sort of double evolution. At least, that's what Ashton assumed.
[She turned into an 'Insane Vampire' at first, but as soon as she had fill, she evolved into something else? This is the first time I have seen something like this.]
