But Lily doesn't live in the care home, so you can't expect her to be around all the time. Elektra lives there and is one of the main characters, and this is the second episode in succession she hasn't really had anything to do.
I'm sure we'll see more of Elektra soon, she's bound to have a central episode in the future. Other characters need more screen time too which is probably why we've seen less of Elektra. But she isn't the only one who we've seen less of. We haven't seen much of Harry and Floss either.
