ooh yes! so, dust extracting ellie? i'm so very down with this! :D not sure how familiar you are with tlou canon, but ellie was extracted just at the point where [SPOILER ALERT IN CASE YOU AREN'T FAMILIAR WITH THE GAME AND PLAN ON PLAYING IT?!] she basically drowned in the tunnel.

ellie definitely is not going to be in a lighthearted place but she'll be frantically trying to cope by pretending everything is fine, be that through asking way too many questions or sharing dumb puns. so, yes. someone for ellie to banter with and trade lighthearted jibes is awesome. :D
