this is a montage type page; sometimes it's tough showing greater spans of time passing in comics without having a clumsy narration box, which doesn't usually bother me in movies but always seem annoying to me in comics. another option is having a character mention the time span in dialogue, like "i've been doing this for days/weeks/etc.!" but that's also kind of tricky because it can seem awkward.
anyway, it isn't always successful but i think the extra-wide panel gutters work pretty well, to me it visually suggests the passage of greater amounts of time between the panels. in my printed comics i also use a lot of blank "beat" pages, sort of a fade-to-black kind of thing inbetween some scenes, but those don't work online because i don't want to do updates where i post just a blank black page. XD
i think Shadoweyes might be the only superhero who keeps a stuffed animal in her secret lair.
