five

When five and lila were trapped in the subway for 5 years, you couldn't find five, you went to Klaus and told him to give you a reading

You wanted to know where your boyfriend was, unfortunately when Klaus saw what five was doing, he saw how lila and five were in a relationship

As soon as you found out about all this you started to think about what to do with it, you went to Diego and told him everything that happened, at first he didn't believe you until you showed him what Klaus saw

Some time later, five and lila returned, but it was no longer the same. Now Diego had another partner and you stayed with Ben to go somewhere else as brothers.

Everyone was at Mr. Reginal's house, the Umbrellas' father. You were talking to Ben, until Five and Lila arrived. When you saw them, you already knew everything, along with Diego, but he wanted to see if they were telling the truth.

why did they disappear?
Diego said

you said

I cheat on you five, and in the apocalypse you decide to do something to leave everything behind
