#On a less-dark note I just realized that Stolas is now a ''secretary bird'' lol

Comparatively minor next to everything OP mentioned, but it's also worth noting that back in Ghostfuckers (canonically set in either November or early December since Apology Tour was set on Halloween) Blitz had been confirmed to have drained both Moxxie and Millie's pensions during his unsuccessful attempt at retail therapy.

While it's possible that the sheer amount of work they got between Mastermind and Sinsmas thanks to Satan's broadcast may have gotten I.M.P. out of the red, we see that Blitz still can't even pay for some new clothes for Stolas, so what does that say about Moxxie and Millie's financial security both in the present AND going forward? They've probably already had to cut back on A LOT of luxuries and possibly even necessities while they slowly get back up to a financially safe place in the interim, and we know all-too-well just how unforgiving Hell can be to imps.

Even without all the foes they've accumulated over the past year (in-universe) breathing down their necks, and even with Moxxie getting more confident with melee combat and Loona getting into a more proactive role at I.M.P. thanks to Stolas taking on the job of I.M.P.'s new secretary (read: Millie needing to take maternity leave won't hurt their business too badly overall), it's still a scary position to be in.

When Millie reveals that she's pregnant, she's unsure of what to do and hasn't even told Moxxie. While it could be pre-birth jitters many women have when they first learn they're pregnant, she might have more to fear.

Her and Moxxie's line of work is a very dangerous one. There's no guarantee that they can survive every mission they get, leaving their kid a potential orphan should Millie choose to give birth. But I.M.P has many enemies in Hell who're out for their blood, be it Striker, Crimson and of course Andrealphus, whose ass they kicked literally just hours prior. Millie has more to be worried about outside the typical pregnancy fears.
